WebbStep 1: Write the equation in the general form a { {x}^2}+bx+c=0 ax2 + bx+ c = 0, where a, b, and c are real numbers, and a ≠0. Step 2: Move the constant c to the right hand side of the equation: a { {x}^2}+bx+c-c=0-c ax2 + bx +c − c = 0 − c a { {x}^2}+bx=-c ax2 + bx = −c Step 3: Divide the equation by the coefficient a: WebbIf you have a general quadratic equation like this: ax^2+bx+c=0 ax2 + bx + c = 0 Then the formula will help you find the roots of a quadratic equation, i.e. the values of x x where …

WebbSome quadratic expressions can be factored as perfect squares. For example, x²+6x+9=(x+3)². However, even if an expression isn't a perfect square, we can turn it into one by adding a constant number. For example, x²+6x+5 isn't a perfect square, but if we add 4 we get (x+3)². This, in essence, is the method of *completing the square*. Webb24 sep. 2024 · Quadratic formula for complex numbers. where a, b and c are complex numbers and a ≠ 0.
