What happens to the discriminant when the quadratic equation has rational coefficients?

The discriminant, b2 - 4ac, offers valuable information about the "nature" of the roots of a quadratic equation where a, b and c are rational values. It quickly ... Summary. The symbol over the b2-4ac is called a 'radical', or a square root symbol; ' ± ' means 'plus or minus'; The DISCRIMINANT is the expression under ... There will be at most two real solutions to any quadratic equation. The value of b2 − 4ac (known as the discriminant) tells us how many real solutions there are ... Jun 4, 2020 ... I wish I could use b^2-4ac>0 to check whether the people are real or not. If b2−4ac > 0 the equation has two distinct real number roots. Example. Study some of these examples: Find the roots of x2 + where both square roots are to be considered when b2 − 4ac 6= 0,. (b) Use the result in part (a) to find the roots of the equation z2 + 2z + (1 − i) = 0. Jan 21, 2020 ... Meoh789 Play Hard Win All The Best Online Games. b± b. 2 4ac. 2a. E= dV dx. F=q E. V = 1. 4.
