How to solve a linear quadratic system
WebStep 1: Find the value of one of the variables using any one of the equations. In this case, let us find the value of 'x' from equation (1). x + y = 6 --------- (1) x = 6 - y. Step 2: Substitute the value of the variable found in step 1 in the second linear equation. WebWhen we get down to the factored formula (x+4) (x-3)=0, then we use the zero property principle that the others have described to finish the solution. The next step is to set each factor equal to zero by itself and solve. (x+4) = 0 x + 4 -4 = 0 -4 x = -4 First solution for x (x-3) = 0 x-3 +3 = +3 x = 3 Second solution for x ( 10 votes) Show more...
