Solve t^4-16 - ScanMath

Evaluate

t^{4} - 16

Rewrite the expression in exponential form

(t^{2})^{2} - (1 6^{\frac{1}{2}})^{2}

Use a^{2} - b^{2} = (a - b) (a + b) to factor the expression

(t^{2} - 1 6^{\frac{1}{2}}) (t^{2} + 1 6^{\frac{1}{2}})

Evaluate

More Steps

(t^{2} - 4) (t^{2} + 1 6^{\frac{1}{2}})

Evaluate

More Steps

(t^{2} - 4) (t^{2} + 4)

Solution

More Steps

(t - 2) (t + 2) (t^{2} + 4)

Factor the expression
