How to solve quadratic systems
WebWhen solving a linear-quadratic system of equations using substitution, you want to plug in the second equation into the first one. Then, combine like terms, simplify, and factor! Let's do a practice problem. Solve the following linear-quadratic system of equations: y=2x2−9x+4 y=4x−2. x=2, x=6. x=12, x=6. WebMar 2, 2024 · If one of the equations looks more complicated than the other, just plug it into the easier equation. Plug x = 3 into the equation x - 6y = 4 to solve for y. 3 - 6y = 4. -6y = 1. Divide -6y and 1 by -6 to get y = -1/6. You have solved the system of equations by addition. (x, y) = (3, -1/6) 5. Check your answer.
