Q. For the following quadratic equation, find the discriminant.x2+4x+32=2xAnswer:
Rearrange equation: Bring all terms to one side of the equation to get it into standard quadratic form ax2+bx+c=0. Subtract 2x from both sides of the equation x2+4x+32=2x to get x2+2x+32=0.
Identify coefficients: Identify the coefficients a, b, and c in the standard form of the quadratic equation.From x2+2x+32=0, we have a=1, b=2, and c=32.
Calculate discriminant: Use the discriminant formula D=b2−4ac to find the discriminant of the quadratic equation.Substitute a=1, b=2, and c=32 into the formula to get D=(2)2−4(1)(32).
Calculate discriminant: Use the discriminant formula D=b2−4ac to find the discriminant of the quadratic equation.Substitute a=1, b=2, and c=32 into the formula to get D=(2)2−4(1)(32).Calculate the discriminant.D=4−128=−124.
