factor 9x^2-25y^2

factor

9 x^{2} - 25 y^{2}

(3 x + 5 y) (3 x - 5 y)

Solution steps

9 x^{2} - 25 y^{2}

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

25 y^{2} = (5 y)^{2}

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

Apply Difference of Two Squares Formula:

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

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

= (3 x + 5 y) (3 x - 5 y)

0 \leq 3 x - 1 \leq 17

\frac{2 ( 1.9 )}{1.6}

0.9 5^{2}

3 (2 + w) - w = 6 + 2 (w + 1)

73 \cdot 3
