Question

fafactorise factorise m square Plus 14 m + 49 ​

Answer 1

Answer:

-7

Step-by-step explanation:

• $m {2} + 7m + 7m + 49$
• $m(m + 7) + 7(m + 7)$
• $(m + 7) (m + 7) = 0$
• $m = - 7$

$\large{ \sf{factorise \: \: {m}^{2} + 14m + 49}}$

$\large{ \green{ \bold{ \underline{ \underline{Answer...}}}}}$

$\large{ \sf{ (m + 7)(m + 7)}}$

$\large{ \sf{ \to \: by \: middle \: term \: factorisation..}} \\ \\ \large{ \sf{ = {m}^{2} + 14m + 49}} \\ \\ \large{ \sf{ = {m}^{2} + 7m + 7m + 49}} \\ \\ \large{ \sf{ = m(m + 7) + 7(m + 7)}} \\ \\ \large{ \sf{ \green{ \boxed{ = (m + 7)(m + 7)}}}}$
