Question

Type the correct answer in each box.Consider these quadratic expressions:A. -3x^2+ 11x-3B. 11x^2- x + 10C. 4x^2 + 27x - 28D.-3x^2 + 11x + 31

Answer 1

Given expression,

$(5x^2+2x+1)+(6x^2-3x+9)=(11x^2-x+10)$

Option B is correct.

$(-3x^2+6x-12)+(5x+9)=(-3x^2+11x-3)$

Option A is correct.

$(8x+16)-(3x^2-3x-15)=(-3x^2+11x+31)$

Option D is correct.

$(5x^2+23x-7)-(x^2-4x+21)=(4x^2+27x-28)$

Option C is correct.
