Answer 1

Hey mate, here is your step-by-step solution

Answer:

m^2 + 4m/3 -50/9

Step-by-step explanation:

    (m + 2/3) (m-7/3)

=> (m + 2/3) (m - (9/3 - 2/3)) [pay attention here!]

=> (m + 2/3) (m - 3 + 2/3)

Taking m + 2/3 as a we get:

=> a (a -3)

=> a^2 - 3a

Replacing the values of a with m+2/3 we get:

=> (m + 2/3)^2 - 3(m + 2/3)

=> m^2 + 4/9 + 4m/3 - 3m - 6

=> m^2 + 4m/3 -50/9

Answer 2

Answer:

$(m+\frac{2}{3}) (m-\frac{7}{3} )$ = $m^{2} -\frac{5}{3}x-\frac{14}{9}$

Step-by-step explanation:

$(m+\frac{2}{3}) (m-\frac{7}{3} )$

By the identity

$(x+a) (x+b) = x^{2} +(a+b)x+ab$

= $m^{2}+ (\frac{2}{3} +(-\frac{7}{3} ))x + \frac{2}{3} *(-\frac{7}{3} )$

=$m^{2} -\frac{5}{3}x-\frac{14}{9}$
