X = −6 ± √ (16) 10. X = − b ± b 2 − 4 a c 2 a. Let’s try this for an equation that is hard to factor: X = −b ± √ (b2 − 4ac) 2a. Use the discriminant to predict the number of solutions of a quadratic equation.
We could just apply the quadratic formula. We can use a method called completing the square. X = − ( − 8) ± ( − 8) 2 − 4 ( 1) ( 5) 2 ( 1) x = 8 ± 64 − 20 2. He then graphs the equations to show that this is true.
X = − ( − 8) ± ( − 8) 2 − 4 ( 1) ( 5) 2 ( 1) x = 8 ± 64 − 20 2. The previous example can be solved by factoring as follows: Web so, when does a quadratic have no solution?

Quadratic formula (no real solutions) Math, Algebra, Quadratic
X = −6 ± √ (62 − 4×5×1) 2×5. Visually, this means the graph of the quadratic (a parabola) will never touch the x axis. Click the blue arrow to submit. Solves by factoring, square.
He then graphs the equations to show that this is true. The solution is real if “ d ” is > 0. We could just apply the quadratic formula. At this point, we need to call upon the straightforward approach of the quadratic formula to find the solutions of the quadratic equation or put simply, determine the values of. X = −0.2 or −1.
The quadratic equation has no real solutions for δ < 0. That will be the number of solutions. Consider the equation x 2 + 6 x = − 2.
Consider The Equation X 2 + 6 X = − 2.
This means we have two distinct solutions. X = −6 ± √ (16) 10. For equations with real solutions, you can use the graphing tool to visualize the solutions. 2x + 3 = 0 or x − 5 = 0 2x = − 3 x = 5 x = − 3 2.
