Really need some help
1. 14x^2+4+3x-12x^2-3+11x
A) 2x^2+7x+1
B) 2x^2+14x+1
C) 2x^2+14x+7
D) 26x^2+7x+7

2. 4x^2+4-5x+x-2x^2+8
A) -2x^2+4x+12
B) -2x^2-4x+12
C) 2x^2+4x+12
D) 2x^2-4x+12

  1. Damon

    14 x^2 -12 x^2 = 2 x^2

    3 x + 11 x = 14 x

    4 - 3 = 1
    so
    2 x^2 + 14 x + 1

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

    -5 x + 1 x = - 4 x

    +4 + 8 = 12

    so what do you think ?

    gather like terms..combine...simplify
    2. x^2(4-2)+x(-5+1)+8+4
    2x^2-4x+12
