Question

Select the correct answer.

Answer 1

Answer:

-4x^2 + 3x +1 & it would be C. quadratic trinomial

Step-by-step explanation:

1: Remove the parenthesis. Switch the -1 to a +1.

8x^2 + 3x - 12x^2+1

2: Simply the equation.

8x^2 + 3x - 12x^2+1

 (2a. Group like terms)

= 8x^2 -12x^2+3x+1

 (2b. Add the similar elements)

= -4x^2 + 3x + 1

So you would minus 12x^2 and 8x^2 to get 4x^2!

Answer 2

Quadratic trinomial
