Question

find the product
(1) (2 x - 5) (X + 2 )
(ii) (x+7)(4x+2)​

Answer 1

Step-by-step explanation:

(2×-5)(X+2)= -5

(X+7)(4x+2)=42x

Answer 2

Answer:

(i) (2x - 5)(x + 2)

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

2x² + 4x - 5x - 10

2x² - x - 10

(ii) (x + 7)(4x + 2)

x(4x + 2) + 7(4x + 2)

4x² + 2x + 28x + 14

4x² + 30x + 14
