We have to subtract: $\left(-4{a}^{2}+6a+10\right)-\left(2{a}^{2}-6a-4\right)$
The subtraction for the polynomials can be given as:
$\left(-4{a}^{2}+6a+10\right)-\left(2{a}^{2}-6a-4\right)$
$=\left(-4{a}^{2}-2{a}^{2}\right)+\left(6a+6a\right)+\left(10+4\right)$
$=-6{a}^{2}+12a+14$
which is the required solution
