Question

Add the given polynomials. 3x^2 – 3x – 2 and -4x^2+ 6x – 21) x^2+3x+42) x^2-3x-43) x^2-3x+44) -x^2+3x-4

Answer 1

the given expression is,

3x^2 – 3x – 2 and -4x^2+ 6x – 2

sum the equation,

= 3x^2 – 3x – 2 + ( -4x^2+ 6x – 2)

= 3x^2 – 3x – 2 - 4x^2+ 6x – 2

= -x^2 + 3x - 4

thus, the answer is option D
