Q. Solve the system of equations.y=32x2+32x−23y=32x+9Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: We have the system of equations:y=32x2+32x−23y=32x+9Set the two equations equal to each other to find the x-values where they intersect.32x2+32x−23=32x+9
Subtract and Simplify: Subtract 32x and 9 from both sides to move all terms to one side and set the equation to zero.32x2+32x−23−32x−9=32x+9−32x−932x2−32=0
Factor Common Term: Factor out the common term 32 from the left side of the equation.32(x2−1)=0
Factor Difference of Squares: Recognize that x2−1 is a difference of squares and can be factored further.32(x+1)(x−1)=0
Set Factors Equal: Set each factor that contains an x equal to zero and solve for x.(x+1)=0 and (x−1)=0x=−1 and x=1
Substitute and Solve: Substitute the x-values back into either original equation to find the corresponding y-values. We'll use y=32x+9. For x=−1: y=32(−1)+9y=−32+9y=−23 For x=1: y=32(1)+9y=32+9y0
Write Coordinates: Write the coordinates in exact form.First Coordinate: (−1,−23)Second Coordinate: (1,41)
