Given a≠±b and a^2−b^2 / a+b =12, find a−b.<br> pls hlep

Readme [11.4K]

Answer:

a - b = 12

Step-by-step explanation:

Given

$\frac{a^2-b^2}{a+b}$ = 12 ← factor the numerator

a² - b² ← is a difference of squares and factors as

a² - b² = (a - b)(a + b)

Thus

$\frac{(a-b)(a+b)}{a+b}$ = 12

Cancel the common factor (a + b) on numerator/ denominator, thus

a - b = 12
