Question

Find the product using the identity
(x + a) (x + b) = x² + (a+b)x+ ab.
a. (2x - 7y) (2x + 8y)
b. 103 x 95
c. 505 x 502
d. (5p -7q) (5p - 7q)​

Answer 1

Step-by-step explanation:

ANSWER

Consider the given equation.

(2x−7y)(2x+8y) ........... (1)

We know that the product identity,

(x+a)(x+b)=x

2

+(a+b)x+ab

Now, from equation (1), we get

(2x−7y)(2x+8y)=4x

2

+(−7y+8y)x−56y

2

=4x

2

+2xy−56y
