Solve the following quadratic equation by factorization:
$\frac{4}{x}-3=\frac{5}{2x+3}, x ≠0,\frac{-3}{2}$
Given:
Given quadratic equation is $\frac{4}{x}-3=\frac{5}{2x+3}, x ≠0,\frac{-3}{2}$.
To do:
We have to solve the given quadratic equation by factorization.
Solution:
$\frac{4}{x}-3=\frac{5}{2x+3}$
$\frac{4-3(x)}{x}=\frac{5}{2x+3}$
$\frac{4-3x}{x}=\frac{5}{2x+3}$
$(2x+3)(4-3x)=5(x)$ (on cross multiplication)
$8x-6x^2+12-9x=5x$
$-6x^2-x+12=5x$
$6x^2+5x+x-12=0$
$6x^2+6x-12=0$
$6(x^2+x-2=0)$
$x^2+x-2=0$
$x^2-2x+x-2=0$
$x(x-2)+1(x-2)=0$
$(x-2)(x+1)=0$
$x-2=0$ or $x+1=0$
$x-2=0$ or $x+1=0$
$x=2$ or $x=-1$
The values of $x$ are $-1$ and $2$.
