factor x^4+13x^2+42

Solution

factor

x^{4} + 13 x^{2} + 42

Solution

(x^{2} + 6) (x^{2} + 7)

Solution steps

x^{4} + 13 x^{2} + 42

Let

u = x^{2}

= u^{2} + 13 u + 42

Factor

u^{2} + 13 u + 42 : (u + 6) (u + 7)

= (u + 6) (u + 7)

Substitute back

u = x^{2}

= (x^{2} + 6) (x^{2} + 7)

Popular Examples

(x+3)(x-3)=16-2x^2

(x + 3) (x - 3) = 16 - 2 x^{2}

\frac{x - 1}{x - 3} < 0

factor 3x^2-12x+12 factor

3 x^{2} - 12 x + 12

simplify ((-2)^3*2^{-4})/(2^{-3)}simplify

\frac{( - 2 ) ^{3} \cdot 2 ^{- 4}}{2 ^{- 3}}

simplify 2+1/6 simplify

2 + \frac{1}{6}
