Question

(4x + 3y) (4x – 3y) can be simplified using
(a+b)2 = a2 +2ab + b2
B (a−b)2 = a2 − 2ab + b2
C (x+a) (x+b) = x2 + (a+b) x + ab
D (a + b) (a – b) = a2 – b2

Answer 1

Answer :

• (a + b) (a - b) = a² - b²

Given :

• An equation (4x + 3y) (4x - 3y).

To Find :

• Simplify this.

Solution :

It can be simplified using :

(a + b) (a - b) = a² - b²

Now

→ (4x)² - (3y)²

→ 16x² - 9y²

Hence, the answer is 16x² - 9y².
