Explanation

We are given the following system of equations:


\begin{gathered} y=2x^2-6x+3 \\ y=x-2 \end{gathered}

We are required to determine the solutions to the given system of equations.

This is achieved thus:


\begin{gathered} y=2x^2-6x+3 \\ y=x-2 \\ \\ \therefore2x^2-6x+3=x-2 \\ 2x^2-6x-x+3+2=0 \\ 2x^2-7x+5=0 \\ \text{ Using grouping method, we have} \\ 2x^2-2x-5x+5=0 \\ (2x^2-2x)(-5x+5)=0 \\ 2x(x-1)-5(x-1)=0 \\ (x-1)(2x-5)=0 \\ x-1=0;2x-5=0 \\ x=1;2x=5 \\ x_1=1;x_2=(5)/(2) \end{gathered}

Hence, the answer is:


x_1=1;x_2=(5)/(2)
