Question

Factors of x² + 15x + 36 are​

Answer 1

Step-by-step explanation:

x² +15x + 36 = 0

x² + 12x + 3x + 36 = 0

x(x + 12 ) + 3(x + 12 ) = 0

(X +3) (x+12 ) = 0

X = -3, -12

Answer 2

${x}^{2} + 15x + 36 \\ \\ = > {x}^{2} + 12x + 3x + 36 \\ \\ = > x(x + 12) + 3(x + 12) \\ \\ = > ( x + 12)(x + 3)$
