Question

using equality formula solve for x x square + (b square minus AC bracket x minus 20 equals to zero​

Answer 1

Solution

Given :

$ab {x}^{2} + (b - ac)x - bc = 0$

factorizing the given equation,

$= > ab {x}^{2} + {b}^{2} x - acx - bc = 0$

$= > \: bx(ax + b) - c(ax - b) = 0$

$= > (bx - c)(ax + b) = 0$

Solving the above equation for x, we get

$(bx - c) = 0 \: or \: (ax + b) = 0$

$x = \frac{c}{b} \: or \: x = \frac{ - b}{a}$

hope this will hep you. ...
