Question

Divide the polynomials.
Your answer should be a polynomial.
22
49
x +7

Answer 1

Answer:

x - 7

Step-by-step explanation:

Given

$\frac{x^2-49}{x+7}$

x² - 49 is a difference of squares and factors as (x - 7)(x + 7)

= $\frac{(x-7)(x+7)}{x+7}$ ← cancel x + 7 on the numerator/ denominator

= x - 7

Answer 2

Answer:

Formula used: a²-b²=(a-b)(a+b)

$★\:\:\frac{( {x}^{2} - 49) }{(x + 7)} = \frac{ ({x}^{2} - {7}^{2} ) }{(x + 7)} = \frac{(x - 7)(x + 7)}{(x + 7)} =\boxed{ (x - 7)}$

(x-7) is the right answer.
