Question

solve m2-11m-42 solve​

Answer 1

Answer:

heya mate ☺

$m ^{2} - 11m - 42 = 0 \\ \\ = > m ^{2} - (14 - 3)m - 42 = 0 \\ \\ = > m ^{2} - 14m + 3m - 42 = 0 \\ \\ = > m(m - 14) + 3(m - 14) = 0 \\ \\ = > (m - 14)(m + 3) = 0 \\ \\ either \: m - 14 = 0 \\ \\ = > m = 14 \\ \\ or \: m + 3 = 0 \\ \\ = > m = - 3$

♡ hope it helps u mate ♡

Answer 2

Answer:

(m-14)(m+3)

Step-by-step explanation:

m²-11m-42

[splitting the middle term]

= m²-14m+3m-42

=m(m-14)+3(m-14)

[now take common as (m-14)]

=(m-14)(m+3)
