How to solve simple quadratic equations
WebFirst step, make sure the equation is in the format from above, ax^2 + bx + c = 0 ax2 +bx +c = 0: x^2+4x-21=0 x2 + 4x − 21 = 0 a a is the coefficient in front of x^2 x2 , so here a = 1 a = 1 (note that a a can’t equal 0 0 -- the x^2 x2 is what makes it a quadratic). b b is the … WebTo solve a linear and quadratic system: Isolate one of the two variables in one of the equations. In most cases, isolating y y is easier. Substitute the expression that is equal to the isolated variable from Step 1 into the other equation. This should result in a quadratic equation with only one variable.
