Expand and simplify

(x + 7) (x + 8)

1 answer

Using the distributive property, we can expand the expression:

(x + 7) (x + 8) = x(x) + x(8) + 7(x) + 7(8)

Simplifying each term by multiplying:

= x^2 + 8x + 7x + 56

Combining like terms:

= x^2 + 15x + 56

Therefore, (x + 7) (x + 8) = x^2 + 15x + 56.
