Q. Solve using the quadratic formula.7h2+3h−9=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.h=_____ or h=_____
Identify coefficients: Identify the coefficients a, b, and c in the quadratic equation7h2+3h−9=0 by comparing it to the standard form ax2+bx+c=0.a=7, b=3, c=−9
Substitute values: Substitute the values of a, b, and c into the quadratic formula, h=2a−b±b2−4ac.h=2(7)−(3)±(3)2−4(7)(−9)
Calculate discriminant: Calculate the discriminant, which is the part under the square root in the quadratic formula: b2−4ac. Discriminant = (3)2−4(7)(−9)=9+252=261
Insert discriminant: Insert the discriminant back into the quadratic formula and simplify.h=2(7)−3±261h=14−3±261
Calculate solutions: Calculate the two possible solutions for h by considering both the positive and negative square roots.h=14−3+261 or h=14−3−261
Round values: Round the values of h to the nearest hundredth, if necessary.h≈(14−3+16.16) or h≈(14−3−16.16)h≈1413.16 or h≈14−19.16h≈0.94 or h≈−1.37
