factor x^3-7x^2+4x-28

factor

x^{3} - 7 x^{2} + 4 x - 28

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

Solution steps

x^{3} - 7 x^{2} + 4 x - 28

= (x^{3} - 7 x^{2}) + (4 x - 28)

Factor out

x^{2}

from

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

Factor out

4

from

4 x - 28 : 4 (x - 7)

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

Factor out common term

x - 7

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

(y + 4)^{3}

(a + bi) (c + d i)

20 \cdot 8

(a + 9) (- a + 9)

162 \cdot 2
