factor 3x^2-20x-63

factor

3 x^{2} - 20 x - 63

(3 x + 7) (x - 9)

Solution steps

3 x^{2} - 20 x - 63

Break the expression into groups

= (3 x^{2} + 7 x) + (- 27 x - 63)

Factor out

x

from

3 x^{2} + 7 x : x (3 x + 7)

Factor out

- 9

from

- 27 x - 63 : - 9 (3 x + 7)

= x (3 x + 7) - 9 (3 x + 7)

Factor out common term

3 x + 7

= (3 x + 7) (x - 9)

7 - 1.5 a + (0.5 a - 5.5) = 2 a + 0.75 - (0.5 + 0.5 a)

4 (2 x - 3) + 2 (x - 4) = 10

(x + 4) (x - 7) = 0

\frac{3}{10} x - 3 x + \frac{6}{5} = \frac{3}{5}

\frac{5}{( 7 - x ) ^{2}} > 0
