Math Problem Statement

expand and simplify (x + 2)(x - 3)

Solution

To expand and simplify (x+2)(x3)(x + 2)(x - 3), apply the distributive property (often called FOIL for binomials):

(x+2)(x3)=x(x)+x(3)+2(x)+2(3)(x + 2)(x - 3) = x(x) + x(-3) + 2(x) + 2(-3)

Now, simplify each term:

  1. xx=x2x \cdot x = x^2
  2. x(3)=3xx \cdot (-3) = -3x
  3. 2x=2x2 \cdot x = 2x
  4. 2(3)=62 \cdot (-3) = -6

Combine all terms:

x23x+2x6x^2 - 3x + 2x - 6

Combine like terms:

x2x6x^2 - x - 6

So, the expanded and simplified form is:

x2x6x^2 - x - 6
