Q. Solve the system of equations.y=x2−31x−1y=−29x+34Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: We have the system of equations:y=x2−31x−1y=−29x+34To find the intersection points, set the two equations equal to each other.x2−31x−1=−29x+34
Form Quadratic Equation: Bring all terms to one side to form a quadratic equation.x2−31x−1+29x−34=0x2−2x−35=0
Factor Quadratic Equation: Factor the quadratic equation.We look for two numbers that multiply to −35 and add up to −2. These numbers are −7 and 5.x2−7x+5x−35=0(x−7)(x+5)=0
Solve for x: Solve for x.Set each factor equal to zero and solve for x.(x−7)=0 or (x+5)=0x=7 or x=−5
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=−29x+34.For x=7:y=−29(7)+34y=−203+34y=−169For x=−5:y=−29(−5)+34y=145+34y=179
Write Coordinates: Write the coordinates in exact form.The intersection points are (7,−169) and (−5,179).
