Question

USE SUITABLE IDENTITIES TO FIND THE PRODUCT:(x+4) (x+10) ​

Answer 1

Answer:

$( x + 4)(x + 10) = x {}^{2} + (4 + 10)x + 4 \times 10 \\ \: \: \: \: \: \: \: = x {}^{2} + 14x + 40$

Using identity

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

Where a = 4 and b = 10

Answer 2

Answer: x^2 + 14x + 40

Step-by-step explanation:(x+4)(x+10)

Using (x+a) (x+b) = x^2 + (a+b) x + ab,

putting a=4,b=10

=x^2 + (4+10) x +4*10

=x^2 + 14x + 40
