Question

Find the Multiplication of the following…..


I) (x + 8) (x – 10)

II) (3 – 2x) (3 + 2x)​

Answer 1

Step-by-step explanation:

I) (x + 8) (x – 10)

= x^2 + 8x -10x -80

x^2 -2x -80

II) (3 – 2x) (3 + 2x)

= 9 -6x +6x-4x^2

9-4x^2

Answer 2

Answer:

1) = x (x) + 8 (x) - x (10) - 8 (10)

= x² + 8x - 10x - 80

= x² - 2x - 80

2) By identity of [(a² - b²) = (a+b) (a-b)],

3² - (2x)²

= 9 - 4x²
