factor 81x^2-25x^2

Solution

factor

81 x^{2} - 25 x^{2}

Solution

56 x^{2}

Solution steps

81 x^{2} - 25 x^{2}

Rewrite

81 x^{2}

as

(3^{2} x)^{2}

Rewrite

25 x^{2}

as

(5 x)^{2}

= (3^{2} x)^{2} - (5 x)^{2}

Apply Difference of Two Squares Formula:

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

(3^{2} x)^{2} - (5 x)^{2} = (3^{2} x + 5 x) (3^{2} x - 5 x)

= (3^{2} x + 5 x) (3^{2} x - 5 x)

Simplify

(3^{2} x + 5 x) (3^{2} x - 5 x) : 56 x^{2}

= 56 x^{2}
