An equation like ax² + bx + c = 0, can be solved by using the quadratic equation formula: x =-b ±√b² - 4ac2a or x =-b ±√Δ2a Where Δ(Delta)= b² - 4ac See step-by-step solution below: Identify the coefficients ...
Example 10: Solving a Quadratic Equation with the Quadratic Formula Use the quadratic formula to solve x2+x+2=0x2+x+2=0. Solution First, we identify the coefficients: a=1,b=1a=1,b=1, and c=2c=2. Substitute these values into the quadratic formula. x=−b±√b2−4ac2a=−...
where a is the coefficient of x^2 b is the coefficient of x c is the constant. Since 2x^2 - x = 3 can rewrite as : 2x^2 - 1x - 3 = 0 So the coefficients of this equation is a=2 for x^2 b= - 1 for x c= - 3 is the constant. To slove it We have to...
