To multiply the expression \((x + 3)(x - 2)\), we can use the distributive property (also known as the FOIL method for binomials):
\[
(x + 3)(x - 2) = x(x) + x(-2) + 3(x) + 3(-2)
\]
Calculating each term:
- \(x(x) = x^2\)
- \(x(-2) = -2x\)
- \(3(x) = 3x\)
- \(3(-2) = -6\)
Now, combine these terms:
\[
x^2 - 2x + 3x - 6
\]
Combine like terms:
\[
x^2 + (3x - 2x) - 6 = x^2 + 1x - 6 = x^2 + x - 6
\]
So, the result of multiplying \((x + 3)(x - 2)\) is:
\[
x^2 + x - 6
\]
The correct answer is:
**x2 + x - 6** (x squared plus x minus 6)
\[
(x + 3)(x - 2) = x(x) + x(-2) + 3(x) + 3(-2)
\]
Calculating each term:
- \(x(x) = x^2\)
- \(x(-2) = -2x\)
- \(3(x) = 3x\)
- \(3(-2) = -6\)
Now, combine these terms:
\[
x^2 - 2x + 3x - 6
\]
Combine like terms:
\[
x^2 + (3x - 2x) - 6 = x^2 + 1x - 6 = x^2 + x - 6
\]
So, the result of multiplying \((x + 3)(x - 2)\) is:
\[
x^2 + x - 6
\]
The correct answer is:
**x2 + x - 6** (x squared plus x minus 6)
