Question

factorise 4x^2-8x-2​

Answer 1

hey dude !!!

$4x \times 2 - 8 x - 2$

$8x - 32 {x}^{2} - 8x$

hope this helps you

Answer 2

Step-by-step explanation:

hey guys!!!!!

$4 {x}^{2} - 8x - 2$

$d = {b}^{2} - 4ac$

${8}^{2} - 4 \times 4 \times - 2$

$64 - 32$

$32$

$x = - \frac{b + - \sqrt{d} }{2a}$

$x = \frac{8 + - \sqrt[4]{2} }{2 \times 4}$

$x = \frac{4(2 + - \sqrt{2)} }{8}$

$x = \frac{2 + - \sqrt{2} }{2}$

hope it may help you
