Question

9/16-25x² factorize ​

Answer 1

Given

9/16 - x^2

factories

solution

9/16- 25x^2

(3/4)^2 - (5x)^2

(3/4 - 5x)(3/4 + 5x)

using identity

a^2 - b^2 = (a +b)(a - b)

Answer 2

Answer:

$\frac{9}{16} - 25 {x}^{2} \\ \frac{9}{16} = 2 5{x}^{2} \\ \frac{9}{16} = (5x) {}^{2} \\ \sqrt{ \frac{9}{16} } = 5x \\ \frac{3}{4} = 5x \\ \frac{3}{4} \times \frac{1}{5} = x \\ \frac{3}{20} = x$
