Q. Solve the system of equations.y=x2+26x−50y=26x+50Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: Set the two equations equal to each other since they both equal y.y=x2+26x−50y=26x+50x2+26x−50=26x+50
Subtract to Zero: Subtract 26x+50 from both sides to set the equation to zero.x2+26x−50−26x−50=0x2−100=0
Factor Quadratic Equation: Factor the quadratic equation. x2−100=(x+10)(x−10)
Solve for x: Set each factor equal to zero and solve for x.(x+10)=0 or (x−10)=0x=−10 or x=10
Substitute for y(−10): Substitute x=−10 into y=26x+50 to find the corresponding y-value.y=26(−10)+50y=−260+50y=−210
Substitute for y (10): Substitute x=10 into y=26x+50 to find the corresponding y-value.y=26(10)+50y=260+50y=310
Write Coordinates: Write the coordinates in exact form.First Coordinate: (−10,−210)Second Coordinate: (10,310)
