Question

factorize
(lm+l)+m+1​

Answer 1

lm + l + m + 1

= lm + m + l + 1

= m(l + 1) + 1(l + 1).

= (m + 1)(l + 1).

Answer 2

Answer:

Step-by-step explanation:

             PLZ MARK AS BRAINLIEST PLZ JUST 1

Split       lm + l + m + 1  

            into two 2-term polynomials

             + l + lm   and     + m + 1

            This partition did not result in a factorization. We'll try another one:

            lm + l   and     + m + 1

            This partition looks good

1.2       Pull out from each binomial separately

            lm + l   =   l • (m + 1)

             + m + 1   =    + 1 • (m + 1)

1.3       Add up to arrive at the desired factorization

            (l + 1) • (m + 1)
