factor 2r^2-9r+9

factor

2 r^{2} - 9 r + 9

(2 r - 3) (r - 3)

Solution steps

2 r^{2} - 9 r + 9

Break the expression into groups

= (2 r^{2} - 3 r) + (- 6 r + 9)

Factor out

r

from

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

Factor out

- 3

from

- 6 r + 9 : - 3 (2 r - 3)

= r (2 r - 3) - 3 (2 r - 3)

Factor out common term

2 r - 3

= (2 r - 3) (r - 3)

4 x^{2} + 8 x + 4 = 1

\frac{1}{9 ( 3 x + 5 ) ^{3}} \leq 0.001

∣ 7 - 3 x ∣ = 3

21 x + 1 = 18 x + 13

6 x + 4 = 9 x - 5
