Solution

factor

c^{2} - 9

Solution

(c + 3) (c - 3)

Solution steps

c^{2} - 9

Rewrite

9

as

3^{2}

= c^{2} - 3^{2}

Apply Difference of Two Squares Formula:

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

c^{2} - 3^{2} = (c + 3) (c - 3)

= (c + 3) (c - 3)

Popular Examples

\frac{a}{4} = 3 - \frac{a - 3}{5}

simplify 4/3-3 simplify

\frac{4}{3} - 3

factor (x^2+2)(m-n)+2(m-n)factor

(x^{2} + 2) (m - n) + 2 (m - n)

1/3 (y+8)+8= 1/6 (9y-24)-4

\frac{1}{3} (y + 8) + 8 = \frac{1}{6} (9 y - 24) - 4

simplify (y^2)/(y^5)simplify

\frac{y ^{2}}{y ^{5}}
