how to use the discriminant

Use the discriminant of the given function to predict how many solutions it has. Also check if the solutions are real or imaginary. 5 x 2 - 5 x + 4 = 0 => 2 real solutions or 1 real and 1 imaginary solution or 2 imaginary solutions or none of the above..

Use the discriminant of the given function to predict how many solutions it has. Also check if the solutions are real or imaginary. 49 x 2 + 182 x + 169 = 0 => 1 real and 1 imaginary solution or 2 real solutions or 2 imaginary solutions or None of the above..

Use the discriminant of the given function to predict how many solutions it has. Also check if the solutions are real or imaginary. 9 x 2 + 17 x - 9 = 0 => 2 imaginary solutions or 2 real solutions or 1 real and 1 imaginary solution or None of the above..

Match the function with its graph, using the discriminant y = 4 x 2 - 2. => Graph-3 or Graph-2 or Graph-1 or none of the above..

Using the value of the discriminant, determine whether 2 x 2 - 3 x - 2 = 0 has two solutions, one solution, or no solution. => One or Two or Zero..

Use the discriminant to find the nature of the solutions of the given quadratic equation. 16 x 2 - 56 x + 49 = 0 => two real, rational, unequal numbers or two real, irrational, unequal numbers or two complex conjugate numbers or real and rational number (double)..

Use the discriminant to find the nature of the solutions of the given quadratic equation. 10 x 2 + 8 x + 9 = 0 => two real, irrational, unequal numbers or two complex conjugate numbers or two real, rational, unequal numbers or one real, rational number (double)..

Use the discriminant to find the nature of the solutions of the given quadratic equation. 6 x 2 - 13 x + 1 = 0 => one real, rational number (double) or two real, rational, unequal numbers or two real, irrational, unequal numbers or two complex conjugate numbers..

Use the discriminant to find the nature of the solutions of the given quadratic equation. 5 x ( x + 4) + 40 = 0 => two real, rational, unequal numbers or one real, rational number (double) or two real, irrational, unequal numbers or two complex conjugate numbers..

Which of the following can be the discriminant of the graph of the quadratic equation? => b 2 - 4 ac = 4 or b 2 - 4 ac = 0 or b 2 - 4 ac = 2 or b 2 - 4 ac = 8..
