Question

Multiply :
(-10mn^2 x (5m - 3n)​

Answer 1

Step-by-step explanation:

((5•(m4))-(10•(m3)))+5m2 = 0 Factoring m2 - 2m + 1

The first term is, m2 its coefficient is 1 .

The middle term is, -2m its coefficient is -2 .

The last term, "the constant", is +1

Step-1 : Multiply the coefficient of the first term by the constant 1 • 1 = 1

Step-2 : Find two factors of 1 whose sum equals the coefficient of the middle term, which is -2 .

-1 + -1 = -2 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -1 and -1

m2 - 1m - 1m - 1

Step-4 : Add up the first 2 terms, pulling out like factors :

m • (m-1)

Add up the last 2 terms, pulling out common factors :

1 • (m-1)

Step-5 : Add up the four terms of step 4 :

(m-1) • (m-1)

Which is the desired factorization
