factor 7y^{-1}+3y^{-2}

factor

7 y^{- 1} + 3 y^{- 2}

\frac{7 y + 3}{y ^{2}}

Solution steps

7 y^{- 1} + 3 y^{- 2}

Apply exponent rule:

a^{b + c} = a^{b} a^{c}

y^{- 1} = y^{- 2} y

= 7 y^{- 2} y + 3 y^{- 2}

Factor out common term

y^{- 2}

= y^{- 2} (7 y + 3)

Refine

= \frac{7 y + 3}{y ^{2}}

e^{2} - 2 e

(x + y)^{2} - 12 (x + y) + 20

(x + 5)^{2} - 2 (x + 5) - 63

(x + 1)^{2} - 6
