factor 0.04a^2-0.49b^2

factor

0.04 a^{2} - 0.49 b^{2}

(0.2 a + 0.7 b) (0.2 a - 0.7 b)

Solution steps

0.04 a^{2} - 0.49 b^{2}

Rewrite

0.04 a^{2} - 0.49 b^{2}

(0.04 a)^{2} - (0.49 b)^{2}

= (0.04 a)^{2} - (0.49 b)^{2}

Apply Difference of Two Squares Formula:

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

(0.04 a)^{2} - (0.49 b)^{2} = (0.04 a + 0.49 b) (0.04 a - 0.49 b)

= (0.04 a + 0.49 b) (0.04 a - 0.49 b)

0.04 = 0.2

= (0.2 a + 0.49 b) (0.04 a - 0.49 b)

0.49 = 0.7

= (0.2 a + 0.7 b) (0.04 a - 0.49 b)

0.04 = 0.2

= (0.2 a + 0.7 b) (0.2 a - 0.49 b)

0.49 = 0.7

= (0.2 a + 0.7 b) (0.2 a - 0.7 b)

2 π r^{2} + 10 π r - 336

\frac{- 27}{7}

x 49 a 4 b 4 - 16 c

\frac{( 1 - r ^{3} )}{1 - r}
