Expanding the Product of Two Binomials: (x+3)(x+2)
When we multiply two binomials, we need to follow the distributive property of multiplication over addition. In this case, we want to expand the product of (x+3)
and (x+2)
.
Step 1: Multiply the First Terms
Multiply the first terms of each binomial: x
and x
.
x × x = x²
Step 2: Multiply the Outer Terms
Multiply the outer terms: x
and 2
.
x × 2 = 2x
Step 3: Multiply the Inner Terms
Multiply the inner terms: 3
and x
.
3 × x = 3x
Step 4: Multiply the Last Terms
Multiply the last terms: 3
and 2
.
3 × 2 = 6
Step 5: Combine Like Terms
Now, combine all the terms we've obtained:
x² + 2x + 3x + 6
Combine the like terms:
x² + 5x + 6
And that's the final answer! The expansion of (x+3)(x+2)
is indeed x² + 5x + 6
