Q. Solve using the quadratic formula.8h2+2h−4=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.h=_____ or h=_____
Quadratic Formula Definition: The quadratic formula is given by h=2a−b±b2−4ac, where a, b, and c are the coefficients of the quadratic equationax2+bx+c=0. In this case, a=8, b=2, and c=−4.
Calculate Discriminant: First, calculate the discriminant, which is the part under the square root in the quadratic formula: b2−4ac. Here, it is 22−4(8)(−4).
Discriminant Calculation: Perform the calculation: 22−4(8)(−4)=4+128=132.
Insert Values into Formula: Now, insert the values of a, b, and the discriminant into the quadratic formula: h=2×8−2±132.
Simplify Formula: Simplify the quadratic formula: h=16−2±132.
Calculate Possible Values: Calculate the two possible values for h: h=16−2+132 and h=16−2−132.
Simplify Square Root: Simplify the square root of 132 to its simplest radical form, which is 4×33=233. So, the formula becomes h=16−2±233.
Factor Out Common Factor: Now, factor out the common factor of 2 in the numerator: h=162(−1±33).
Simplify Fraction: Simplify the fraction by dividing both the numerator and the denominator by 2: h=8−1±33.
Write Solutions: Finally, write the two solutions for h: h=8−1+33 or h=8−1−33.
