Question

Factorise the following expression: $-4a^2+4ab-4ac$

Answer 1

Factorise the given expression by splitting the like terms

Given, $-4a^2+4ab-4ac$

The like term in this expression is $4a$

Upon splitting the like term, factorisation will be $4a(-a+b-c)$.

Therefore, $-4a^2+4ab-4ac$ can be factorised as $4a(-a+b-c)$.
