factor 64x^2-81y^2

factor

64 x^{2} - 81 y^{2}

(8 x + 9 y) (8 x - 9 y)

Solution steps

64 x^{2} - 81 y^{2}

64 x^{2} = (8 x)^{2}

81 y^{2} = (9 y)^{2}

= (8 x)^{2} - (9 y)^{2}

Apply Difference of Two Squares Formula:

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

(8 x)^{2} - (9 y)^{2} = (8 x + 9 y) (8 x - 9 y)

= (8 x + 9 y) (8 x - 9 y)

4 x^{2} + 7 x = 0

\frac{( x ^{3} y ^{2} ) ^{\frac{3}{2}}}{( x ^{- 1} y ^{- \frac{2}{3}} ) ^{\frac{1}{4}}}

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

6 (x + 1) + 2 \geq 5 x + 12

x^{2} + 10 x + 25
