factor t^2+2t-15

factor

t^{2} + 2 t - 15

(t - 3) (t + 5)

Solution steps

t^{2} + 2 t - 15

Break the expression into groups

= (t^{2} - 3 t) + (5 t - 15)

Factor out

t

from

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

Factor out

5

from

5 t - 15 : 5 (t - 3)

= t (t - 3) + 5 (t - 3)

Factor out common term

t - 3

= (t - 3) (t + 5)

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

x^{2} + 9 x = 36

8 + 10 f > 14 - 2 f

\frac{x}{- 4} - 8 \geq - 9

\frac{25}{9} x^{2} - 36
