Quadratic formula worksheet real solutions quadratic formula worksheet complex solutions quadratic formula worksheet both real and complex solutions discriminant worksheet. False example x2 10 2 create your own worksheets like this one with infinite algebra 2. Solve quadratic equations by completing the square.
True 20 if a quadratic equation cannot be factored then it will have at least one imaginary solution. There are four different methods used to solve equations of this type. When solving linear equations such as 2x 5 21 we can solve for the variable directly by adding 5 and dividing by 2 to get 13.
I can solve by completing the square. The equation 𝑥 t w has only one solution 𝑥 w while the quadratic equation 𝑥2 t w has two solutions 𝑥 w and 𝑥 w. I can solve by factoring.

1 k 1 k 5. Factoring method if the quadratic polynomial can be factored the zero product property may be used. Solve quadratic equations by factoring.
I can use the discriminant to determine the number and type. However when we have x2 or a higher power of x we cannot just isolate the variable as we did with the linear equations. If you are unsure why the quadratic equation 𝑥2 t w has two real solutions instead of just one try solving it by factoring.
I can perform operations with imaginary numbers. Factorize the constant term in such a way that its factors give the middle term coefficient when added and apply the zero product rule to obtain the real roots.
I can solve by taking the square root. I can solve equations using the quadratic formula with rationalized denominators. Create your own worksheets like this one with infinite algebra 1.
