factor s^2-4

Solution

factor

s^{2} - 4

Solution

(s + 2) (s - 2)

Solution steps

s^{2} - 4

Rewrite

4

as

2^{2}

= s^{2} - 2^{2}

Apply Difference of Two Squares Formula:

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

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

= (s + 2) (s - 2)

Popular Examples

(2-2x)/(3x+2)<= 0

\frac{2 - 2 x}{3 x + 2} \leq 0

3 x - 5 \geq 2

\frac{4 x + 6}{2} - 3 = 14

simplify (9!)/((9-5)!)simplify

\frac{9 !}{( 9 - 5 ) !}

(5x)/4-3/17 (x-20)-(2x-1)=(x+24)/(34)

\frac{5 x}{4} - \frac{3}{17} (x - 20) - (2 x - 1) = \frac{x + 24}{34}
