Question

factorize 9x^2-1/16​

Answer 1

a2−b2=(a+b)(a−b). 9x2−16 =(3x)2−(4)2. (3x)2−(4)2=(3x−4)(3x+4).

If my answer is correct please mark me as brainliest and give me a like

Answer 2

$9x {}^{2} - \frac{1}{16}$

we can write

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

NOW WE WILL USE THIS FORMULA

$(a - b) {}^{2} = a ^{2} + b^{2} - 2ab$

HERE WE WILL ASSUME

$a = (3x) ^{2} \:$

$b = ( \frac{1}{4} ) {}^{2}$

NOW PUTTING THEIR VALUES IN ABOVE EQUATION.....
