Q. Solve using the quadratic formula.2h2−5h−1=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.h=_____ or h=_____
Identify values: Identify the values of a, b, and c in the quadratic equation2h2−5h−1=0. By comparing the equation to the standard form ax2+bx+c=0, we find: a=2b=−5c=−1
Substitute in formula: Substitute the values of a, b, and c into the quadratic formula to find h. The quadratic formula is h=2a−b±b2−4ac. So we have: h=2⋅2−(−5)±(−5)2−4⋅2⋅(−1)
Simplify expression: Simplify the expression under the square root and the constants outside the square root.h=45±25−(−8)h=45±25+8h=45±33
Identify possible values: Identify the two possible values for h.h=45+33 or h=45−33
Round to nearest hundredth: If necessary, round the values of h to the nearest hundredth.h≈(5+5.74)/4 or h≈(5−5.74)/4h≈10.74/4 or h≈−0.74/4h≈2.685 or h≈−0.185
