 Step 1 Enter the equations 1 y=x^23x 2 y=62x Step 2 Solve for one of the variables in terms of the other 2 y=62x Since this is already done for us, we can go on to the next step Step 3 Substitute Equation 2 in Equation 1 and solve for x 62x=x^23x x^2 5x6=0 (x6)(x1)=0 x6=0 and x1=0 x=6 and x1 Step4Add '225' to each side of the equation 3x 225 x 2 = 2 225 Reorder the terms 225 3x x 2 = 2 225 Combine like terms 2 225 = 425 225 3x x 2 = 425 Factor a perfect square on the left side (x 15)(x 15) = 425 Calculate the square root of the right side Break this problem into two subproblems byΔ = b 24ac Δ = 3 24·(1)·(1) Δ = 5 The delta value is higher than zero, so the equation has two Answered Locity And 3 30 Y 2x 2 In Exercises 5 Bartleby Y=x^2-3x+1
