factor x^2+3x-28

factor

x^{2} + 3 x - 28

(x - 4) (x + 7)

Solution steps

x^{2} + 3 x - 28

Break the expression into groups

= (x^{2} - 4 x) + (7 x - 28)

Factor out

x

from

x^{2} - 4 x : x (x - 4)

Factor out

7

from

7 x - 28 : 7 (x - 4)

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

Factor out common term

x - 4

= (x - 4) (x + 7)

\frac{x + 4}{3} + \frac{x}{2} = 1

8 x^{2} + 64 x + 120 = 0

(\frac{4 x y}{5 x ^{2} y ^{- 2}})^{2}

36 - 4.9 (x)^{2} = 10

(\frac{2}{7})^{2}
