4c^{2}-6c-10=\left(c+1\right)\left(4c-3\right)
Use the distributive property to multiply 2c+2 by 2c-5 and combine like terms.
4c^{2}-6c-10=4c^{2}+c-3
Use the distributive property to multiply c+1 by 4c-3 and combine like terms.
4c^{2}-6c-10-4c^{2}=c-3
Subtract 4c^{2} from both sides.
-6c-10=c-3
Combine 4c^{2} and -4c^{2} to get 0.
-6c-10-c=-3
Subtract c from both sides.
-7c-10=-3
Combine -6c and -c to get -7c.
-7c=-3+10
Add 10 to both sides.
-7c=7
Add -3 and 10 to get 7.
c=\frac{7}{-7}
Divide both sides by -7.
c=-1
Divide 7 by -7 to get -1.
