Question

(6x2 - 4x – 5) – (3x2 – 7x + 2)

Answer 1

Answer: 3x2 + 3x - 7

Step-by-step explanation: The first term is, 3x2 its coefficient is 3

The middle term is, +3x its coefficient is 3

The last term, the constant, is -7

1.Multiply the coefficient of the first term by the constant 3 times -7 = -21

2. Find two factors of -21 whose sum equals the coefficient of the middle term, which is 3

Answer 2

3x^2 + 3x - 7

Explanation:

1. Distribute the - sign to 3x^2 - 7x + 2

(6x^2 - 4x - 5) - 3x^2 + 7x - 2

2. Combine like terms 6x^2 and 3x^2

^ - 4x - 5 + 7x - 2

3. Combine like terms -4x and 7x

3x^2 + - 5 - 2

4. Finally combine like terms -5 and -2

3x^2 + 3x -

So your final answer is 3x^2 + 3x - 7!

I hope this helped :)
