Question

Subtract the sum of a(a + b) and b (a - b) from a^2 - 3ab + 2b^2.​

Answer 1

Answer:

3ab−2a2−2b2−(5a2−7ab+5b2)3ab−2a2−2b2−5a2+7ab−5b210ab−7a2−7b2

Answer 2

Answer:

3b²-5ab

Step-by-step explanation:

First u will do sum

It is given that Subtractt the sum of a(a + b) and b (a - b)

sum of a(a + b) and b (a - b)

a²+ab+ab-b²

a²-b²+2ab ------------------(i)

Then, Subtract from a²-3ab+2b²----------------(ii)

Subtract eq. (i) from (ii)

a²-3ab+2b²-(a²-b²+2ab)

a²-3ab+2b²-a²+b²-2ab

a²-a²+2b²+b²-3ab-2ab

3b²-5ab

correct explanation
