2(x + 2)(x + 8)
Assuming you want the expression factorised.
Take out a common factor of 2
= 2(x² + 10x + 16) → ( factor the quadratic )
Consider the factors of the constant term which sum to give the coefficient of the x term
that is, the factors of + 16 which sum to + 10 are + 2 and + 8
= 2(x + 2)(x + 8) → ' in factored form '
