Q. For the following quadratic equation, find the discriminant.x2−16x+51=4x−2Answer:
Rephrase the Question: First, let's rephrase the "What is the discriminant of the quadratic equation x2−16x+51=4x−2?"
Standard Form Conversion: To find the discriminant, we need to write the quadratic equation in the standard form ax2+bx+c=0. Let's move all terms to one side of the equation to do this.x2−16x+51−(4x−2)=0
Combine Like Terms: Now, let's simplify the equation by combining like terms. x2−16x+51−4x+2=0x2−20x+53=0
Identify Coefficients: The standard form of a quadratic equation is ax2+bx+c=0. In our equation, a=1, b=−20, and c=53.
Calculate Discriminant Formula: The discriminant of a quadratic equation is given by the formula D=b2−4ac. Let's calculate the discriminant using the values of a, b, and c we found.D=(−20)2−4(1)(53)
Perform Calculations: Now, let's perform the calculations.D=400−4(53)D=400−212
Find Discriminant Value: Finally, let's subtract 212 from 400 to find the value of the discriminant.D=188
