Question

value of (x+5) (x + 2) by using suitable identity​

Answer 1

Answer:

$\huge\underline\mathfrak\red{solution}$

here we have to use identity (lV)

using identity :- (X+a) (X+b)= a² + ( a+ b)x + (ab)

$\huge\underline\mathfrak\orange{let's find out:-}$

we have :-

==>>(x+5) (x+2) = x² + (5+2)x + (5)(2)

==>> (x+5) (x+2) = x² + 7x + 10

==>> x² + 7x + 10

:. hence the value of (x+5) (x+2) is x² + 7x + 10
