Q. Solve using the quadratic formula.6p2+3p−2=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.p=_____ or p=_____
Identify values: Identify the values of a, b, and c from the quadratic equation6p2+3p−2=0. Compare 6p2+3p−2=0 with the standard form ax2+bx+c=0. a=6b=3c=−2
Substitute into formula: Substitute the values of a, b, and c into the quadratic formula p=2a−b±b2−4ac. Substitute a=6, b=3, and c=−2 into the quadratic formula. p=2⋅6−(3)±(3)2−4⋅6⋅(−2)
Simplify and calculate: Simplify the expression under the square root and calculate the discriminant.(3)2−4⋅6⋅(−2)= 9+48= 57
Calculate solutions: Calculate the two possible solutions for p.p=2⋅6−3±57p=12−3±57p=12−3+57 or p=12−3−57
Round and approximate: Simplify the solutions and round to the nearest hundredth if necessary.p=12−3+57 or p=12−3−57Since 57 is approximately 7.55, we can approximate the solutions.p≈12−3+7.55 or p≈12−3−7.55p≈124.55 or p≈12−10.55p≈0.38 or p≈−0.88
