Question

factorise 181-16x^2plss answer my question it's urgent

Answer 1

Given Equation is 181 - 16x^2

$= \ \textgreater \ -(16x^2 - 181)$

$= \ \textgreater \ -(4x)^2 - ( \sqrt{181} )^2$

We know that a^2 - b^2 = (a + b)(a - b)

$= \ \textgreater \ -(4x + \sqrt{181} )(4x - \sqrt{181})$


Hope this helps!
