Question

I need to factor by grouping the equation 6u^2 + 29u - 42

Answer 1

the expression : 6u^2+29u-42
we need to find two factors of 6(-42) that multiply to be 6(-42) and add up to be 29

Answer 2

6u^2+36u-7u-42
then
6u(u+6)-7(u+6)
final answer
(6u-7)(u+6)

Answer 3

so we have 6(-42)=36(-7) and 36-7=29
