# quadratic systems practice quizlet solve the system by substitution

Substitute your answer into the first equation and solve. I have to solve the system. Solve 1 equation for 1 variable. x2+ 4y2º 4 = 0 Equation 1 º2y2+ x + 2 = 0 Equation 2 SOLUTION Because Equation 2 has no x2-term, solve that equation for x. º2y2+ x + 2 = 0 x = 2y2º 2 Next, substitute 2y2 º2for x in Equation 1 and solve for y. x2+ 4y2º 4 = 0 Equation 1 Solving Quadratics by Factoring Solving Quadratics by the Quadratic Formula Quiz: Solving Quadratics by the Quadratic Formula Solving Equations in Quadratic Form Quiz: Solving Equations in Quadratic Form Given the equation for this parabola: y=-(x-4) 2-3, does this parabola have a maximum or minimum value?
