factor y^2+6y-7

factor

y^{2} + 6 y - 7

(y - 1) (y + 7)

Solution steps

y^{2} + 6 y - 7

Break the expression into groups

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

Factor out

y

from

y^{2} - y : y (y - 1)

Factor out

7

from

7 y - 7 : 7 (y - 1)

= y (y - 1) + 7 (y - 1)

Factor out common term

y - 1

= (y - 1) (y + 7)

\frac{1}{- 5. 1 ^{2} - 25}

x^{2} - 2 x - 63

- 4 x + 5 = 20

\frac{1}{x} - \frac{1}{y} - \frac{1}{z}

(5 + x) (11 - x) < 0
