WebSolving a cubic polynomial is nothing but finding its zeros. The general form of a cubic equation is ax 3 + bx 2 + cx + d = 0, a ≠ 0. To solve a cubic equation: Step 1: Re-arrange the equation to standard form Step 2: Break it down to the product of linear factor and quadratic equation Step 3: Then solve the quadratic equation Here, Step 2 can be done … WebWe can use a linear approximation to find a close estimate for the square root. √ (x) ≈ (x + y) / (2 * √ (y)) where y is a number that is "close to" x. Typically, you would choose y to be a perfect square to make the math easy. ( 3 votes) Upvote Downvote Flag svmejia 7 …
Then the above formula becomes, x = (-b ± √0)/2a = -b/2a and hence the equation has only one real root. Thus, the quadratic equation has only one real root (or two equal roots -b/2a and -b/2a) when b2- 4ac = 0. We have seen that the roots of the quadratic equation x2 - 7x + 10 = 0 are x = 2 and x = 5. So the … See more WebIn other words, a quadratic equation is an “equation of degree 2” An equation of the form ax 2 + bx + c = 0, where a ≠ 0 is called a quadratic equation and a, b, c are coefficients of the quadratic equation.
