Q. Solve using the quadratic formula.q2−9q+8=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.q=_____ or q=_____
Write Quadratic Formula: Write down the quadratic formula.The quadratic formula is used to solve equations of the form ax2+bx+c=0. The formula is given by:q=2a−b±b2−4acIn our equation, a=1, b=−9, and c=8.
Substitute Values: Substitute the values of a, b, and c into the quadratic formula.q=2(1)−(−9)±(−9)2−4(1)(8)q=29±81−32q=29±49
Simplify Equation: Simplify the square root and the equation.49 is 7, so we have:q=(9±7)/2This gives us two possible solutions for q.
Solve for Solutions: Solve for the two possible values of q.First solution:q=(9+7)/2q=16/2q=8Second solution:q=(9−7)/2q=2/2q=1
