Q. Solve using the quadratic formula.3q2+7q−6=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.q=_____ or q=_____
Identify coefficients: Identify the coefficients a, b, and c in the quadratic equation3q2+7q−6=0 by comparing it to the standard form ax2+bx+c=0.a=3, b=7, c=−6
Substitute values into formula: Substitute the values of a, b, and c into the quadratic formula, q=2a−b±b2−4ac.q=2(3)−(7)±(7)2−4(3)(−6)
Simplify discriminant: Simplify the expression under the square root, known as the discriminant. (7)2−4(3)(−6)=49+72=121
Calculate square root: Calculate the square root of the discriminant. 121=11
Substitute back into formula: Substitute the square root of the discriminant back into the quadratic formula.q=2×3−7±11
Calculate possible solutions: Calculate the two possible solutions for q.q=6−7+11 or q=6−7−11q=64 or q=6−18
Simplify fractions: Simplify the fractions to their simplest form. q=32 or q=−3
Round non-integer solution: If necessary, round the non-integer solution to the nearest hundredth. q=0.67 or q=−3
