Math Problem Statement

Simplify (-4x + 3)^2

Solution

The problem shown in the image is to simplify the expression (4x+3)2(-4x + 3)^2. Let's solve it step by step.

Step-by-step solution:

We are squaring the binomial (4x+3)(-4x + 3). The formula for squaring a binomial is:

(a+b)2=a2+2ab+b2(a + b)^2 = a^2 + 2ab + b^2

Here:

  • a=4xa = -4x
  • b=3b = 3

Substitute into the formula:

(4x+3)2=(4x)2+2(4x)(3)+32(-4x + 3)^2 = (-4x)^2 + 2(-4x)(3) + 3^2

  1. Calculate (4x)2(-4x)^2: (4x)2=16x2(-4x)^2 = 16x^2

  2. Calculate 2(4x)(3)2(-4x)(3): 2(4x)(3)=24x2(-4x)(3) = -24x

  3. Calculate 323^2: 32=93^2 = 9

Combine all the terms:

(4x+3)2=16x224x+9(-4x + 3)^2 = 16x^2 - 24x + 9

Final Answer:

16x224x+916x^2 - 24x + 9
