How To Solve A Second Degree Equation Quadratic Equation Yout Learn how to solve second degree, also known as, quadratic equations that have only one unknown. also, learn how to figure out how many answers there are to. These quadratic equations have the form ax^2 c=0 ax2 c = 0 and do not have a bx term. to solve these equations, we need to isolate x ² and then take the square root of both sides of the equation. for example, let’s solve the equation x^2 16=0 x2 − 16 = 0. therefore, we have to rearrange it as follows: x^2=16 x2 = 16. Summary. quadratic equation in standard form: ax 2 bx c = 0. quadratic equations can be factored. quadratic formula: x = −b ± √ (b2 − 4ac) 2a. when the discriminant (b2−4ac) is: positive, there are 2 real solutions. zero, there is one real solution. negative, there are 2 complex solutions. A quadratic equation is a polynomial equation in a single variable where the highest exponent of the variable is 2. there are three main ways to solve quadratic equations: 1) to factor the quadratic equation if you can do so, 2) to use the quadratic formula, or 3) to complete the square. if you want to know how to master these three methods.

Example 4: the quad equation 2x 2 9x 7 = 0 has roots α, β. find the quadratic equation having the roots 1 α, and 1 β. solution: method 1: the quadratic equation having roots that are reciprocal to the roots of the equation ax 2 bx c = 0, is cx 2 bx a = 0. the given quadratic equation is 2x 2 9x 7 = 0. Given a quadratic equation that cannot be factored, and with a = 1, first add or subtract the constant term to the right sign of the equal sign. x2 4x 1 = 0 x2 4x = − 1 multiply the b term by 1 2 and square it. 1 2(4) = 2 22 = 4 add (1 2)2 to both sides of the equal sign and simplify the right side.
