Quadratic Formula Definition: The quadratic formula is given by y=2a−b±b2−4ac, where a, b, and c are the coefficients of the quadratic equationay2+by+c=0. In this case, a=2, b=7, and c=6.
Calculate Discriminant: First, calculate the discriminant, which is the part under the square root in the quadratic formula: b2−4ac. For our equation, the discriminant is 72−4(2)(6).
Discriminant Calculation: Perform the calculation: 72−4(2)(6)=49−48=1.
Using Quadratic Formula: Now that we have the discriminant, we can use the quadratic formula. Since the discriminant is positive, we will have two real solutions. Substitute a, b, and the discriminant into the formula to find y.
First Solution Calculation: First solution: y=2×2−7+1=4−7+1=4−6=−23.
Second Solution Calculation: Second solution: y=2×2−7−1=4−7−1=4−8=−2.
