factor x^2-4+8x-15

factor

x^{2} - 4 + 8 x - 15

(x + 4 - 35) (x + 4 + 35)

Solution steps

x^{2} - 4 + 8 x - 15

Group like terms

= x^{2} + 8 x - 4 - 15

Subtract the numbers:

- 4 - 15 = - 19

= x^{2} + 8 x - 19

Solve

x^{2} + 8 x - 19 = 0 : x = - 4 + 35, x = - 4 - 35

Polynom can therefore be factored into

= (x - (- 4 + 35)) (x - (- 4 - 35))

Refine

= (x + 4 - 35) (x + 4 + 35)

(x - a + bi) (a + bi - a - bi)

- 3 sin (2 x + 2)

- 3 + h - 3

l (3 cos (t))

2^{x + 1} - 2^{x}
