Question

Find the product using suitable identity (x+3)(x+8)​

Answer 1

Answer:

HOW TO SOLVE:

(x+3)(x+8)​

This is in the form of

(x+a)(x+b)

The identity for this is=

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

where x=x

a=3

b=8

$x^{2} + (3+8)x+ (3*8)$

$x^{2} + 11x+ 24$

CONFIRMATION:

(x+3)(x+8)​

Through normal multiplication

= $x^{2} +8x+3x+24\\= x^{2} +11x+24$

hence, confirmed

Hope this helps u :)

Answer 2

Answer:

Step-by-step explanation:

Using the identity: (x + a)(x + b) = x² + (a + b) x + ab.

(x+3)(x+8)= x² +(3+8)x +(3)(8)

                =  x²+ 11x + 24

thus answer is : x² + 11x + 24
