Simplify (x+6)(x-7)

$(x + 6) (x - 7)$

Step 1

Expand $(x + 6) (x - 7)$ using the FOIL Method.

Apply the distributive property.

$x (x - 7) + 6 (x - 7)$

Apply the distributive property.

$x \cdot x + x \cdot - 7 + 6 (x - 7)$

Apply the distributive property.

$x \cdot x + x \cdot - 7 + 6 x + 6 \cdot - 7$

$x \cdot x + x \cdot - 7 + 6 x + 6 \cdot - 7$

Step 2

Simplify and combine like terms.

Simplify each term.

Multiply $x$ by $x$ .

$x^{2} + x \cdot - 7 + 6 x + 6 \cdot - 7$

Move $- 7$ to the left of $x$ .

$x^{2} - 7 \cdot x + 6 x + 6 \cdot - 7$

Multiply $6$ by $- 7$ .

$x^{2} - 7 x + 6 x - 42$

$x^{2} - 7 x + 6 x - 42$

Add $- 7 x$ and $6 x$ .

$x^{2} - x - 42$

$x^{2} - x - 42$
