Question

What is this expression plz work out x2+5x-24​

Answer 1

(x + 8)(x - 3)

Explanation:

Assuming you require to factor the expression.

Given

x² + 5x - 24

Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (+ 5)

The factors are + 8 and - 3, since

8 × - 3 = - 24 and 8 - 3 = + 5, thus

x² + 5x - 24 = (x + 8)(x - 3) ← in factored form

Answer 2

(x - 3)(x + 8)

Explanation:

x² + 5x - 24 =

= x² + 8x - 3x - 24

= x(x + 8) - 3(x + 8)​

= (x - 3)(x + 8)
