Question
Factorize:
$-4a^2+ 4ab - 4ca$
$-4a^2+ 4ab - 4ca$
✓
Answer
The greatest common factor of the term
$-4a^2+ 4ab$ and 4ca of the expression
$-4a^2+ 4ab - 4ca$
Also, we can write $-4a^2= (-4a.a), 4ab = -4a.(-b) - 4ca$ and $4ca = (-4a.c)$
Therefore, $-4a^2+ 4ab - 4ca = (-4a.a) + (-4a.(-b)) - (4a.c)$
$-4a(a - b)$
$-4a^2+ 4ab$ and 4ca of the expression
$-4a^2+ 4ab - 4ca$
Also, we can write $-4a^2= (-4a.a), 4ab = -4a.(-b) - 4ca$ and $4ca = (-4a.c)$
Therefore, $-4a^2+ 4ab - 4ca = (-4a.a) + (-4a.(-b)) - (4a.c)$
$-4a(a - b)$
