what algebraic expression must be added to the sum of 3x squared + 4x + 8 and 2x squared -6x + 3 to give 9x squared -2x - 5 as t
gregori [183]
<span>3x^2 + 4x + 8 + 2x^2 - 6x + 3 to give result as 9x^2 -2x - 5


</span>3x^2 + 4x + 8 + 2x^2 - 6x + 3 
= 5x^2 - 2x + 11

so

9x^2 -2x - 5 - (5x^2 - 2x + 11)
= 9x^2 -2x - 5 -  5x^2 +  2x - 11
= 4x^2 -16

answer

expression (4x^2 -16) must be added to the sum of (3x^2 + 4x + 8) and (2x^2 - 6x + 3) to give the result as (9x^2 - 2x - 5)

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 9(3)ˣ

x = -1

<u>Step 2: Solve</u>

  1. Substitute:                    f(-1) = 9(3)⁻¹
  2. Evaluate:                       f(-1) = 9(1/3)
  3. Multiply:                        f(-1) = 9/3
  4. Divide:                           f(-1) = 3
