# How do you factor x^4 + 10x^2 + 16 ?

${x}^{4} + 10 {x}^{2} + 16 = \left({x}^{2} + 2\right) \left({x}^{2} + 8\right)$

#### Explanation:

The given expression is

${x}^{4} + 10 {x}^{2} + 16$

The factors of 16 are 2 and 8 which when added results to 10.

${x}^{4} + 10 {x}^{2} + 16 = \left({x}^{2} + 2\right) \left({x}^{2} + 8\right)$

God bless....I hope the explanation is useful.
