Step-by-step explanation:
Hey, there!!
Let's do it simply, ok.
Given that,
[tex] = - 2 {x}^{2} + 8x + 10[/tex]
Take (-2) common to make it easy.
[tex] = -2( 2 {x}^{2} - 8x - 10)[/tex]
= -2{ x^2-(5-1)x -5}
Multily with x,
= -2 {x^2-5x+x-5}
Taking common,
= -2{x(x-5) +1(x-5)
= -2{(x+1)(x-5)}...is your required answer.
Hope it helps...
