factor x^4-2x^2-63

Solution

factor

x^{4} - 2 x^{2} - 63

Solution

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

Solution steps

x^{4} - 2 x^{2} - 63

Let

u = x^{2}

= u^{2} - 2 u - 63

Factor

u^{2} - 2 u - 63 : (u + 7) (u - 9)

= (u + 7) (u - 9)

Substitute back

u = x^{2}

= (x^{2} + 7) (x^{2} - 9)

Factor

x^{2} - 9 : (x + 3) (x - 3)

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

Popular Examples

-0.13633(x)^2-3.00066(x)+73.59566=24.91

- 0.13633 (x)^{2} - 3.00066 (x) + 73.59566 = 24.91

10x-4(x+1)>= 13+3x

10 x - 4 (x + 1) \geq 13 + 3 x

factor 5x^2-13xy+6y^2 factor

5 x^{2} - 13 x y + 6 y^{2}

2 x = 8 x - x^{2}

2 x + 5 = - x^{2}
