Question

the expression (2x^2 + 6x + 5) - (6x^2 + 3x + 5) is equivalent to which solution?

1) -4^2 + 3x
2) 4x^2 - 3x
3) -4x^2 - 3x + 10
4) 4x^2 + 3 - 10​

Answer 1

Answer:

1) -4x^2 + 3x

Step-by-step explanation:

you subtract the numbers that have the same exponent and variable!

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

2x^2 - 6x^2 = -4x^2

6x - 3x = 3x

5 - 5 = 0
