factor 49a^2-9b^2

factor

49 a^{2} - 9 b^{2}

(7 a + 3 b) (7 a - 3 b)

Solution steps

49 a^{2} - 9 b^{2}

49 a^{2} = (7 a)^{2}

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

= (7 a)^{2} - (3 b)^{2}

Apply Difference of Two Squares Formula:

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

(7 a)^{2} - (3 b)^{2} = (7 a + 3 b) (7 a - 3 b)

= (7 a + 3 b) (7 a - 3 b)

- (7.7 u - 3 v) + 1.5

- 4 x - 2 (3 z - 2 x)

5. 8^{2}

- (- \frac{1}{2})^{- 1}

\frac{3 ^{4} x ^{4}}{3 x ^{2}}
