factor

h^{2} - 4

Solution

(h + 2) (h - 2)

Solution steps

h^{2} - 4

Rewrite

4

as

2^{2}

= h^{2} - 2^{2}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

h^{2} - 2^{2} = (h + 2) (h - 2)

= (h + 2) (h - 2)

\frac{2 ^{8}}{2 ^{4}}

20=-16t^2+170t+70

20 = - 16 t^{2} + 170 t + 70

simplify (sqrt(5)+1)(sqrt(5)-1)simplify

(5 + 1) (5 - 1)

t^{2} + 3 t = 0
