Question

Subtract the following
1. – x2 + 10x – 5 from 5x – 10
2. 4pq – 5q2 – 3p2 from 5p2 + 3q2 – pq

Answer 1

Step-by-step explanation:

1. – x2 + 10x – 5 from 5x – 10

5x – 10 - (– x2 + 10x – 5)

5x-10+x²-10x+5

x²-5x-5

2. 4pq – 5q2 – 3p2 from 5p2 + 3q2 – pq

5p2 + 3q2 – pq- (4pq – 5q2 – 3p2)

5p2 + 3q2 – pq-4pq+5q2+3p2

8p²+8q²-5pq
