Given Equation is 2(x - 3)^2 - 32
= > 2(x^2 + 9 - 6x) - 32
= > 2x^2 + 18 - 12x - 32
= >2x^2 - 12x - 14
= > 2(x^2 - 6x - 7)
= > 2(x^2 + x - 7x - 7)
= > 2(x(x + 1) - 7(x + 1))
= > 2(x + 1)(x - 7).
(2)
Given Equation is a^2(b + c) - (b + c)^3
= > (b + c)[a^2 - (b + c)^2]
= > (b + c)[(a - (b + c)(a + (b + c)]
= > (b + c)[a - b - c)(a + b + c)]
Hope this helps!
