Question

(X+3) (x+5) factorise

Answer 1

SOLUTION

Given,

(x+3)(x+5)

=) x(x+5)+3(x+5)

=) x² +5x +3x+15

=) x² +8x+ 15

Now, Factorize

${x}^{2} + 8x + 15 = 0 \\ \\ = > {x}^{2} + 3x + 5x + 15 = 0 \\ \\ = > x(x + 3) + 5(x + 3) = 0 \\ \\ = > (x + 3) (x + 5) = 0 \\ \\ = > x + 3 = 0 \: \: \: \: \: or \: \: \: \: x + 5 = 0 \\ \\ = > x = - 3 \: \: \: or \: \: x = - 5$

Hope it helps ☺️

Answer 2

Hey mate ☺️

Step-by-step explanation:

➡️ (x + 3) (x + 5)

Factorisation :

➡️ x = - 3 or x = - 5

➡️ x = - 3, -5

I Hope it helps you ☺️ ✌️ ✌️
