Question

What are the factors of the expression, 2x² - 7x - 15?

Answer 1

(2x+3) (x-5)

Explanation:

2x^2-10x+3x-15

2x(x-5) +3(x-5)

(2x+3) (x-5)

Answer 2

THAT IS AN ALTERNATIVE QAY IF ASKING YOU TO FACTORISE THE EXPRESSION.

`= 2{x}^(2) - 10x + 3x - 15 \\ = ( 2{x}^(2) - 10x) + (3x - 15) \\ = 2x(x - 5) + 3(x - 5) \\ = (x - 5)(2x + 3)`

(x-5)(2x+3) ARE THE FACTORS OF THE

EXPRESSION

GOODLUCK!
