Q. Solve the system of equations.y=x2−43x−14y=−45x+34Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: We have the system of equations:y=x2−43x−14y=−45x+34To find the intersection points, set the two equations equal to each other.x2−43x−14=−45x+34
Form Quadratic Equation: Bring all terms to one side to form a quadratic equation.x2−43x−14+45x−34=0x2+2x−48=0
Factor Quadratic: Factor the quadratic equation.In quadratic equation ax2+bx+c, the factors are of the form (x+m)(x+n).Where b is the sum and c is the product of m and n respectively.x2+2x−48=0(x+8)(x−6)=0
Solve for x: Solve for x.Set each factor equal to zero, and solve for x.(x+8)=0 or (x−6)=0x=−8 or x=6
Find y-values: Find the corresponding y-values for each x-value by substituting back into either of the original equations. We'll use y=−45x+34.For x=−8:y=−45(−8)+34y=360+34y=394
Write Coordinates: For x=6: y=−45(6)+34y=−270+34$y = \(-236\)
Write Coordinates: For \(x = 6\):\[y = -45(6) + 34\]\[y = -270 + 34\]\[y = -236\]Write the coordinates in exact form.\[\text{First Coordinate: } (-8, 394)\]\[\text{Second Coordinate: } (6, -236)\]
