The discriminant is 88 which means that the given quadratic equation has two different solutions for x
Is it possible to find three solutions of the equation x3 plus 2x2 plus 3x plus 6 equals 0 Explain why or why not?
The variable term, X^3, is a third order polynomial term and will render three solutions, though one of those may be zero.
How many solutions will the equation 25 equals 2x squared-6x have?
2x2 - 6x - 25 = 0. Solutions are 5.34 and -2.34
What are the solutions to the simultaneous equations of 3x -y equals 5 and 2x2 plus y2 equals 129?
The solutions work out as: x = 52/11, y = 101/11 and x = -2, y = -11
What is the discriminant of 2x2 plus 5x plus 4?
-7 therefore the quadratic equation has no real roots
How many solutions are there to the equation 2x2 7x 30?
Some plusses and/or minuses would have assisted. (2x - 5)(x + 6) are factors of 2x2 + 7x - 30, giving solutions for x of 2.5 and -6; (2x + 5)(x - 6) are factors of 2x2 - 7x - 30, giving solutions of -2.5 and 6.
What are the factors of the equation 2x2 plus 10 equals 9x?
2x2 + 10 = 9x 2x2 - 9x + 10 = 0 (x - 2)(2x - 5) = 0
Solve this quadratic equation using the quadratic formula 2x2 - 10x plus 7 equals 0?
2x2-10+7 = 0 Solving the quadratic equation using the quadratic formula will give you two solutions and they are: x = (5 - the square root of 11)/2 or x = (5 + the square root of 11)/2
