Question

Factorize :
x^2+8x+15
x^2-2x-15
x^2+9x-36
x^2-12x-45

Answer 1

Factorizing each expression:

x^2 + 8x + 15 = (x+3)(x+5)

x^2 - 2x - 15 = (x-5)(x+3)

x^2 + 9x - 36 = (x+12)(x-3)

x^2 - 12x - 45 = (x-15)(x+3)

So the factorized expressions are:

- x^2 + 8x + 15 = (x+3)(x+5)

- x^2 - 2x - 15 = (x-5)(x+3)

- x^2 + 9x - 36 = (x+12)(x-3)

- x^2 - 12x - 45 = (x-15)(x+3)
