Question

(x + a) (x + b) = ………..​

Answer 1

Answer:

(x+a)(x+b)is equal to x^2-xb-ax-ab=x^2-x(b+a)-ab

or x^2 -b (x+a)-ax

Answer 2

(x + a) (x + b) = x² + (a + b)x + ab

Given :

The expression (x + a) (x + b)

To find :

Simplify the given expression

Solution :

Step 1 of 2 :

Write down the given expression

The given expression is

(x + a) (x + b)

Step 2 of 2 :

Simplify the given expression

$\sf (x + a)(x + b)$

$\sf = x(x + b) + a(x + b)$

$\sf = {x}^{2} + bx + ax + ab$

$\sf = {x}^{2} + (a + b)x + ab$
