4x^{2}-10=3\left(2-3x^{2}\right)
Use the distributive property to multiply 2 by 2x^{2}-5.
4x^{2}-10=6-9x^{2}
Use the distributive property to multiply 3 by 2-3x^{2}.
4x^{2}-10+9x^{2}=6
Add 9x^{2} to both sides.
13x^{2}-10=6
Combine 4x^{2} and 9x^{2} to get 13x^{2}.
13x^{2}=6+10
Add 10 to both sides.
13x^{2}=16
Add 6 and 10 to get 16.
x^{2}=\frac{16}{13}
Divide both sides by 13.
x=\frac{4\sqrt{13}}{13} x=-\frac{4\sqrt{13}}{13}
Take the square root of both sides of the equation.
4x^{2}-10=3\left(2-3x^{2}\right)
Use the distributive property to multiply 2 by 2x^{2}-5.
4x^{2}-10=6-9x^{2}
Use the distributive property to multiply 3 by 2-3x^{2}.
4x^{2}-10-6=-9x^{2}
Subtract 6 from both sides.
4x^{2}-16=-9x^{2}
Subtract 6 from -10 to get -16.
4x^{2}-16+9x^{2}=0
Add 9x^{2} to both sides.
13x^{2}-16=0
Combine 4x^{2} and 9x^{2} to get 13x^{2}.
x=\frac{0±\sqrt{0^{2}-4\times 13\left(-16\right)}}{2\times 13}
This equation is in standard form: ax^{2}+bx+c=0. Substitute 13 for a, 0 for b, and -16 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±\sqrt{-4\times 13\left(-16\right)}}{2\times 13}
Square 0.
x=\frac{0±\sqrt{-52\left(-16\right)}}{2\times 13}
Multiply -4 times 13.
x=\frac{0±\sqrt{832}}{2\times 13}
Multiply -52 times -16.
x=\frac{0±8\sqrt{13}}{2\times 13}
Take the square root of 832.
x=\frac{0±8\sqrt{13}}{26}
Multiply 2 times 13.
x=\frac{4\sqrt{13}}{13}
Now solve the equation x=\frac{0±8\sqrt{13}}{26} when ± is plus.
x=-\frac{4\sqrt{13}}{13}
Now solve the equation x=\frac{0±8\sqrt{13}}{26} when ± is minus.
x=\frac{4\sqrt{13}}{13} x=-\frac{4\sqrt{13}}{13}
The equation is now solved.
