Understanding the Equation: x + 14x = 32
Before diving into factoring, it's essential to understand the structure of the given equation.
Step 1: Combine Like Terms
- The equation x + 14x = 32 involves two terms with x.
- Combine them to simplify the equation:
- x + 14x = 15x
- So, the simplified form is 15x = 32
Step 2: Write the Equation in Standard Form
- To solve quadratic equations by factoring, the equation must be in the form ax² + bx + c = 0.
- Currently, the equation is linear, but to relate it to quadratic form, consider the general approach.
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) ✅
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.
