Q. Solve the system of equations.y=x−18x2+y2=290Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Substitute y Equation: Substitute y from the first equation into the second equation.y=x−18x2+y2=290x2+(x−18)2=290
Expand and Simplify: Expand the second term and simplify the equation. x2+(x2−36x+324)=2902x2−36x+324=290
Subtract to Zero: Subtract 290 from both sides to set the equation to zero.2x2−36x+324−290=02x2−36x+34=0
Divide and Simplify: Divide the entire equation by 2 to simplify.x2−18x+17=0
