factor y^2-9y+18

factor

y^{2} - 9 y + 18

(y - 3) (y - 6)

Solution steps

y^{2} - 9 y + 18

Break the expression into groups

= (y^{2} - 3 y) + (- 6 y + 18)

Factor out

y

from

y^{2} - 3 y : y (y - 3)

Factor out

- 6

from

- 6 y + 18 : - 6 (y - 3)

= y (y - 3) - 6 (y - 3)

Factor out common term

y - 3

= (y - 3) (y - 6)

x^{2} - 2 x - 48 < 0

- 2 + \frac{x}{x + 2} \leq \frac{1 - x}{x - 2}

4 x^{2} - 8 x + 6 = 0

1 - (- \frac{1}{2})^{2}

42 \cdot 4
