factor 3x^2-28x+9

factor

3 x^{2} - 28 x + 9

(3 x - 1) (x - 9)

Solution steps

3 x^{2} - 28 x + 9

Break the expression into groups

= (3 x^{2} - x) + (- 27 x + 9)

Factor out

x

from

3 x^{2} - x : x (3 x - 1)

Factor out

- 9

from

- 27 x + 9 : - 9 (3 x - 1)

= x (3 x - 1) - 9 (3 x - 1)

Factor out common term

3 x - 1

= (3 x - 1) (x - 9)

5^{2} - 8 x + 19 \geq 0

\frac{1}{2} \cdot \frac{2 π}{3}

\frac{5 - 10 x}{17} < 9 + 6 x

\frac{9 !}{( 9 - 2 ) !}

(x + 9)^{2} = 20
