Answer:
[tex]49 {m}^{2} + 70m + 25 [/tex]
Solution,
( 7m + 5)^2
Using the formula:
[tex] {(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2} [/tex]
and expand the expression
= ( 7m)^2 + 2 • 7m • 5 + (5)^2
Evaluate the power
= 49m^2 + 2 • 7m • 5 + 25
Calculate the product
= 49m^2 + 70m + 25
Hope this helps...
Good luck on your assignment..
