Question

factorise 3 l - M whole square + 12 l m​

Answer 1

Answer:

factories 3 = 1×3

factories whole square +12 = 1×2×3×4×6×12

Answer 2

Step-by-step explanation:

(31-m)²+121m

961+m²-62m+121m

m²+59m+961

D=b²-4ac

=(59)²-4(1)((961)

=3481-3844

= -363

Discriminant is negative so it has no real roots therefore it can't be factorised.
