factor a^2-2^2a-15

factor

a^{2} - 2^{2} a - 15

(a - 2 - 19) (a - 2 + 19)

Solution steps

a^{2} - 2^{2} a - 15

Solve

a^{2} - 2^{2} a - 15 = 0 : a = 2 + 19, a = 2 - 19

Polynom can therefore be factored into

= (a - (2 + 19)) (a - (2 - 19))

Refine

= (a - 2 - 19) (a + 19 - 2)

x^{2} + (- 5) x + 25

144 h^{2} + 49 i^{2}

e^{3 I n (x)}

\frac{19}{( e ^{7} ) - 5} + 4

sin (x - k x)
