Question

Pls Factorize the following
x^3 + 9x^2 + 23x + 15

Answer 1

Answer:

(x+1)(x+5)(x+3)

Step-by-step explanation:

Factor out x^2 from the expression:

x^3+x^2+8x+2+8x+15x+15

Factor out x+1 from the expression:

(x^2)x(x+1)+(8x)x(x+1)+15(x+1)

Write 8x as a sum:

(x+1)x(x^2+8x+15)

Factor out x from the expression:

(x+1)x(x^2+5x+3x+15)

Factor out x+5 from the expression:

(x+1)x(xx(x+5)+3(x+5))

Solution:

(x+1)(x+5)(x+3)
