Questions using the quadratic formula to solve \( x^2 + 20 = 2x \) , what are the values of x? More Videos using the quadratic formula to solve \( x^2 + 20 = 2x \) , what are the values of x? Equation is \( x^2 + 20 = 2x \) [Convert Equation to quadratic equation to find the value of x through quadratic formula] \( x^2 -2x+ 20 = 0 \) [According to the Quadratic Equation a= 1, b= -2 and c=20] Quadratic Formula \(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\) [put the value of a, b, and c in the formula] => \(x = {-(-2) \pm \sqrt{(-2)^2-4 \times 1 \times 20} \over 2 \times 1}\) => \(x = {2 \pm \sqrt{4-80} \over 2 }\) => \(x = {2 \pm \sqrt{-76} \over 2 }\) => \(x = \frac{2}{2} \pm \sqrt {\frac{-76}{4} } \) => \(x = 1 \pm \sqrt {-19} \) [The Value of \( \sqrt {-19} = 4.359i] => \(x = 1 \pm 4.359i \) => \(x = 1 – 4.359i \;or\; 1 + 4.359i \) Related posts: using the quadratic formula to solve \( 2x^2 = 4x – 7 \), what are the values of x? which equation shows the quadratic formula used correctly to solve \( 5x^2 + 3x – 4 = 0 \) for x?
