Here is an example with two answers: But it does not always work out like that! Imagine if the curve "just touches" the x-axis. Or imagine the curve is so high it doesn't even cross the x-axis! This is where the "Discriminant" helps us ...
WebSet each factor equal to zero, then solve for x x. x - 5 = 0 x − 5 = 0 implies that x = 5 x = 5 x + 2 = 0 x + 2 = 0 implies that x = - 2 x = −2 So the possible solutions are x = 5 x = 5 and x = - 2 x = −2 . Remember to always substitute the possible solutions back to … WebThe Quadratic Formula: x = − b ± b 2 – 4 a c 2 a.

WebIn mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x. For example, 4 and −4 are square roots of 16, because 4² = (−4)² = 16.
WebSolving by factoring. Suppose we want to solve the equation x^2-3x-10=0 x2 −3x −10 = 0, then all we have to do is factor x^2-3x-10 x2 −3x −10 and solve like before! x^2-3x-10 x2 −3x −10 can be factored as (x+2) (x-5) (x +2)(x −5).
