factor

y^{2} - 2 y - 3

(y + 1) (y - 3)

Solution steps

y^{2} - 2 y - 3

Break the expression into groups

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

Factor out

y

from

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

Factor out

- 3

from

- 3 y - 3 : - 3 (y + 1)

= y (y + 1) - 3 (y + 1)

Factor out common term

y + 1

= (y + 1) (y - 3)

(1 + \frac{0.06}{2})^{2} - 1

6 - \frac{1}{3} x^{2} = - 18

39 \cdot 2

(2^{4} \cdot 6^{4})^{- \frac{1}{4}}

∣ 2 x - 1 ∣ < x
