Let us solve it using the Quadratic Formula:Where a, b and c are from the Quadratic Equation in "Standard Form": ax2 + bx + c = 0Solve 3x2 - 30x - 12 = 0 Coefficients are:a = 3, b = −30 and c = −12 Quadratic Formula:x = [ −b ±√(b2−4ac) ] / 2a ...
such as free fall in a vacuum. The general quadratic equation in one variable isax2+bx+c= 0, in whicha, b,andcare arbitrary constants (or parameters) andais not equal to 0. Such anequationhas two roots (not necessarily distinct), as given by the quadratic formulax=−b±b2−4ac2a...
Do you see b2 − 4ac in the formula above? It is called the Discriminant, because it can "discriminate" between the possible types of answer:when b2 − 4ac is positive, we get two Real solutions when it is zero we get just ONE real solution (both answers are the same) when it ...
Now we can just use the quadratic formula to get our answers, given that a=1, b=2, c= -3:x=−b±√b2−4ac2ax=−b±b2−4ac2a x=−2±√22+122x=−2±22+122 x=−2±√162x=−2±162 x=−2±42x=−2±42 x=−2+42=1 ORx=−2+42=1 OR x=−2−42...

, c is the constant term, and x is the variable. Since the variable x is of the second degree, there are two roots or answers for this quadratic equation. The roots of the quadratic equation can be found by either solving by factorizing or through the use of the quadratic formula....
Solving Quadratics: In general, quadratic equations can be solved using the quadratic formula. That said, when there is no middle term (no value of x with a coefficient), we can simply solve for the square root of the value ofcto find our answer. ...
