17\left(20^{2}+\left(1.5t\right)^{2}-\left(12+1.5t\right)^{2}\right)=10\left(34^{2}+\left(1.5t\right)^{2}-\left(30+1.5t\right)^{2}\right)
Variable t cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 1020t, the least common multiple of 60t,102t.
17\left(400+\left(1.5t\right)^{2}-\left(12+1.5t\right)^{2}\right)=10\left(34^{2}+\left(1.5t\right)^{2}-\left(30+1.5t\right)^{2}\right)
Calculate 20 to the power of 2 and get 400.
17\left(400+1.5^{2}t^{2}-\left(12+1.5t\right)^{2}\right)=10\left(34^{2}+\left(1.5t\right)^{2}-\left(30+1.5t\right)^{2}\right)
Expand \left(1.5t\right)^{2}.
17\left(400+2.25t^{2}-\left(12+1.5t\right)^{2}\right)=10\left(34^{2}+\left(1.5t\right)^{2}-\left(30+1.5t\right)^{2}\right)
Calculate 1.5 to the power of 2 and get 2.25.
17\left(400+2.25t^{2}-\left(144+36t+2.25t^{2}\right)\right)=10\left(34^{2}+\left(1.5t\right)^{2}-\left(30+1.5t\right)^{2}\right)
Use binomial theorem \left(a+b\right)^{2}=a^{2}+2ab+b^{2} to expand \left(12+1.5t\right)^{2}.
17\left(400+2.25t^{2}-144-36t-2.25t^{2}\right)=10\left(34^{2}+\left(1.5t\right)^{2}-\left(30+1.5t\right)^{2}\right)
To find the opposite of 144+36t+2.25t^{2}, find the opposite of each term.
17\left(256+2.25t^{2}-36t-2.25t^{2}\right)=10\left(34^{2}+\left(1.5t\right)^{2}-\left(30+1.5t\right)^{2}\right)
Subtract 144 from 400 to get 256.
17\left(256-36t\right)=10\left(34^{2}+\left(1.5t\right)^{2}-\left(30+1.5t\right)^{2}\right)
Combine 2.25t^{2} and -2.25t^{2} to get 0.
4352-612t=10\left(34^{2}+\left(1.5t\right)^{2}-\left(30+1.5t\right)^{2}\right)
Use the distributive property to multiply 17 by 256-36t.
4352-612t=10\left(1156+\left(1.5t\right)^{2}-\left(30+1.5t\right)^{2}\right)
Calculate 34 to the power of 2 and get 1156.
4352-612t=10\left(1156+1.5^{2}t^{2}-\left(30+1.5t\right)^{2}\right)
Expand \left(1.5t\right)^{2}.
4352-612t=10\left(1156+2.25t^{2}-\left(30+1.5t\right)^{2}\right)
Calculate 1.5 to the power of 2 and get 2.25.
4352-612t=10\left(1156+2.25t^{2}-\left(900+90t+2.25t^{2}\right)\right)
Use binomial theorem \left(a+b\right)^{2}=a^{2}+2ab+b^{2} to expand \left(30+1.5t\right)^{2}.
4352-612t=10\left(1156+2.25t^{2}-900-90t-2.25t^{2}\right)
To find the opposite of 900+90t+2.25t^{2}, find the opposite of each term.
4352-612t=10\left(256+2.25t^{2}-90t-2.25t^{2}\right)
Subtract 900 from 1156 to get 256.
4352-612t=10\left(256-90t\right)
Combine 2.25t^{2} and -2.25t^{2} to get 0.
4352-612t=2560-900t
Use the distributive property to multiply 10 by 256-90t.
4352-612t+900t=2560
Add 900t to both sides.
4352+288t=2560
Combine -612t and 900t to get 288t.
288t=2560-4352
Subtract 4352 from both sides.
288t=-1792
Subtract 4352 from 2560 to get -1792.
t=\frac{-1792}{288}
Divide both sides by 288.
t=-\frac{56}{9}
Reduce the fraction \frac{-1792}{288} to lowest terms by extracting and canceling out 32.
