Question

1. (7x2 – 5x + 3)-(7x2 – 5)​

Answer 1

1. (7x²–5x + 3)-(7x²–5)​=7x²–5x+3-7x²+5=8-5x

Answer 2

To simplify the expression (7x^2 - 5x + 3) - (7x^2 - 5), you need to distribute the negative sign to every term inside the parentheses and then combine like terms:

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

Step 1: Distribute the negative sign: = 7x^2 - 5x + 3 - 7x^2 + 5

Step 2: Combine like terms: = (7x^2 - 7x^2) + (-5x + 5) + 3 = 0x^2 + (-5x + 5) + 3 = -5x + 5 + 3 = -5x + 8

So the simplified expression is: -5x + 8
