Question

M+N = 5 and MN = 6 then (M²-N²)(M³+N³) ?

Answer 1

Answer:

175

Step-by-step explanation:

Given: M+N = 5 , MN = 6

WE KNOW THAT;

(M-N) = (M+N)²- 4MN

(M-N) = (5)^2 - 4*6 = 25-24 = 1

Also, (M²+N²) = (M+N)² - 2MN = 25-12 = 13

Now,

(M²-N²)(M³+N³)

= (M+N)(M-N)(M+N)(M²-MN+N²)

=5*1*5*(13-6)

=25*7 = 175.
