There are infinitely many quadratics that can equal 20.
For example, given any positive number, a, a*x^2 + 20 will equal 20 for x= 0.
20
2x2 + 3x - 20 = (x + 4)(2x - 5).
Because when your solving a quadratic equation your looking for x-intercepts which is where why equals 0 and x equals what ever the answer is.
an equation has an equals sign.
No. [ y = 4x2 ] is a quadratic equation.
Using the quadratic equation formula: x = 1 or x = -10
Quadratic - the degree is two.
It is a quadratic equation that has 2 solutions
No
9x^(2) = 10x + 2 Is a quadratic eq'n. Algebraically rearrange to usual quadratic form . 9x^(2) -10x - 2 = 0 Does NOT factor , so apply Quadratic eq'n
Yes.
Linear.
