Answer:
x^2+4x-77
Step-by-step explanation:
distribute x+11 to x-7
x*x-x^2
x*-7=-7x
11*x=11x
11*-7=-77
combine like terms with -7x and 11x to get 4x
x^2+4x-77
Answer:
x² + 4x - 77
Step-by-step explanation:
To find the product, use the FOIL method. FOIL = First, Outside, Inside, Last.
(x + 11)(x - 7)
First:
(x)(x) = x²
Outside:
(x)(-7) = -7x
Inside:
(11)(x) = 11x
Last:
(11)(-7) = -77
Remember to simplify by combining like terms:
x² - 7x + 11x - 77
x² (-7x + 11x) - 77
x² + 4x - 77
x² + 4x - 77 is your answer.
