factor (x^2)/(25)-9

factor

\frac{x ^{2}}{25} - 9

(\frac{x}{5} + 3) (\frac{x}{5} - 3)

Solution steps

\frac{x ^{2}}{25} - 9

Rewrite

\frac{x ^{2}}{25} - 9

(\frac{1}{25} x)^{2} - 3^{2}

= (\frac{1}{25} x)^{2} - 3^{2}

Apply Difference of Two Squares Formula:

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

(\frac{1}{25} x)^{2} - 3^{2} = (\frac{1}{25} x + 3) (\frac{1}{25} x - 3)

= (\frac{1}{25} x + 3) (\frac{1}{25} x - 3)

Refine

= (\frac{x}{5} + 3) (\frac{x}{5} - 3)

(- 2 t) - (6 t^{2})

π (x + 2)^{2} - π (x - 2)^{2}

- 91 x t - 143 x p + 35 a t + 55 a p

f (t) - 4 + e^{t - 5}

(x + 8) 6 - 2 (x + 8) 5
