Q. Solve the system of equations.y=3x2−6x−33y=−6x+15Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: We have the system of equations:y=3x2−6x−33y=−6x+15Set the two equations equal to each other to find the x-coordinates of the intersection points.3x2−6x−33=−6x+15
Simplify Equation: Simplify the equation by moving all terms to one side.3x2−6x−33+6x−15=03x2−48=0
Divide and Simplify: Divide the equation by 3 to simplify further.x2−16=0
Factor Quadratic Equation: Factor the quadratic equation. x2−16=(x−4)(x+4)
Solve for x: Solve for x by setting each factor equal to zero.(x−4)=0 or (x+4)=0x=4 or x=−4
Find y for x=4: Find the corresponding y-values by substituting x back into one of the original equations. Let's use y=−6x+15. For x=4: y=−6(4)+15y=−24+15y=−9
Find y for x=−4: Find the y-value for x=−4: y=−6(−4)+15 y=24+15 y=39
Write Coordinates: Write the coordinates in exact form.First Coordinate: (4,−9)Second Coordinate: (−4,39)
