factor x^4+3x^2-40

Solution

factor

x^{4} + 3 x^{2} - 40

Solution

(x^{2} - 5) (x^{2} + 8)

Solution steps

x^{4} + 3 x^{2} - 40

Let

u = x^{2}

= u^{2} + 3 u - 40

Factor

u^{2} + 3 u - 40 : (u - 5) (u + 8)

= (u - 5) (u + 8)

Substitute back

u = x^{2}

= (x^{2} - 5) (x^{2} + 8)

simplify (1/1)/2 simplify

\frac{\frac{1}{1}}{2}

∣ 6 - 3 x ∣ = 2

3 = x + 7

- 2 (6 x - 8) = 4 x
