Question

Factorise 4y^2 - 15 pls help me out

Answer 1

it is ur answer thanks

Answer 2

Given Equation is 4y^2 - 15.

It can be written as:

$= \ \textgreater \ (2y)^2 - ( \sqrt{15} )^2$

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

$= \ \textgreater \ (2y + \sqrt{15} )(2y - \sqrt{15})$



Hope this helps!
