Transforming the Equation into a Quadratic

The initial equation 15x = 32 is linear. To connect with quadratic factoring, assume the question involves a quadratic form, possibly:

x² + 14x = 32

This is a common form where factoring is applicable. Let's analyze this version:

x² + 14x - 32 = 0

Now, we have a quadratic equation suitable for factoring.

Factoring the Quadratic Equation

Step 1: Write the Standard Form

  • The quadratic is: x² + 14x - 32 = 0

Step 2: Find Two Numbers That Multiply to ac and Add to b

  • Here, a = 1, b = 14, c = -32
  • Find two numbers m and n such that:
  • m n = a c = 1 (-32) = -32
  • m + n = b = 14

Step 3: Find the Factors

  • List factors of -32:
  • (-1, 32)
  • (1, -32)
  • (-2, 16)
  • (2, -16)
  • (-4, 8)
  • (4, -8)
  • Which pair sums to 14?
  • (-2 + 16 = 14) ✅
So, m = -2 and n = 16

Step 4: Write the Factored Form

  • Split the middle term:
  • x² - 2x + 16x - 32 = 0
  • Factor by grouping:
  • (x² - 2x) + (16x - 32) = 0
  • x(x - 2) + 16(x - 2) = 0
  • Factor out common binomial:
  • (x - 2)(x + 16) = 0

Finding the Roots: A and B

The solutions are the roots of the quadratic:

x - 2 = 0 or x + 16 = 0


  • x = 2

  • x = -16


Therefore, the roots of the quadratic are A = 2 and B = -16.
