Question

what is the sum of x^2+4x-2 and x^2+5x+6

Answer 1

Answer: (A)    2x^2+9x+4

Step-by-step explanation:

x^(2)+4x-2 + x^(2)+5x+6 = 2x^2+9x+4

Answer 2

The sum of x²+4x-2 and x²+5x+6 is; 2x² + 9x -4.

According to the question;

• We are required to determine the sum of the polynomials; x²+4x-2 and x²+5x+6

By adding the individual polynomials; their sum is evaluated as follows;

• x²+4x-2 + x²+5x+6

• = x² + x² + 4x + 5x + 6 -2.

• = 2x² + 9x + 4
