factor 2r^2-r-3

factor

2 r^{2} - r - 3

(r + 1) (2 r - 3)

Solution steps

2 r^{2} - r - 3

Break the expression into groups

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

Factor out

2 r

from

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

Factor out

- 3

from

- 3 r - 3 : - 3 (r + 1)

= 2 r (r + 1) - 3 (r + 1)

Factor out common term

r + 1

= (r + 1) (2 r - 3)

\frac{5 π}{2} - \frac{π}{2}

3 x^{2} + 11 x + 5 = 0

52 + x^{2} = 13

y^{2} - 8 y + 25 = 0

F = 6 F
