Answer:
The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into both terms, you would write x(x + 1) . This video shows you how to solve a quadratic equation by factoring.
Step-by-step explanation:
= x^2 ( x+3 ) (x+3)
= set equal to 0
X^2= 0
X=0
X+3=0
X=-3
Answer is -3 and 0
