simplify (a^2-b^2)/(a+b)

simplify

\frac{a ^{2} - b ^{2}}{a + b}

a - b

Solution steps

\frac{a ^{2} - b ^{2}}{a + b}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

a^{2} - b^{2} = (a + b) (a - b)

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

Cancel the common factor:

a + b

= a - b

3 (x + 5) \leq 0

x^{3} + x^{2} - 10 x + 8 \geq 0

(\frac{20}{29})^{2} - (\frac{21}{29})^{2}

\frac{7}{3} \cdot 2

6 w + 3 = 6 (w + 4) - 21
