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

simplify

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

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

Solution steps

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

Factor

a^{2} - ab : a (a - b)

= \frac{a ( a - b )}{a ^{2} + ab}

Factor

a^{2} + ab : a (a + b)

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

Cancel the common factor:

a

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

0 = - 4.9 t^{2} 2 + 5 t + 185

15 \cdot 35

7 x^{2} + 6 x = - 2

3 x^{2} - 10 x - 25

3 x - 5 = \frac{12 + 4 x}{2}
