Question

Simplify: (5x2 + 3x + 4) + (2x2 − 6x + 3) I keep getting 3x^2 + 9x + 1, and that is not one of the answers.

Answer 1

\(3x-6x=-3x\)

Answer 2

Combine like terms first.

Answer 3

i think you are subtracting, when you should be adding

Answer 4

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

\(\implies x^2(5+2) + x(3-6) + (4+3)\)

Answer 5

Simplify it now and identify your mistake @thedesolusx

Answer 6

The possible answers include
7x^2 + 9x + 7

7x^2 + 3x + 7

7x^2 − 3x + 1

7x^2 − 3x + 7

I have re-calculated and have not gotten anything close to one of the answers... :(
