Q. Solve using the quadratic formula. 7m2−9m+2=0 Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth. m=□ or m=□
Write Quadratic Formula: Write down the quadratic formula.The quadratic formula is used to solve for the roots of a quadratic equationax2+bx+c=0 and is given by x=2a−b±b2−4ac.
Identify Coefficients: Identify the coefficients a, b, and c from the quadratic equation 7m2−9m+2=0. Here, a=7, b=−9, and c=2.
Substitute into Formula: Substitute the coefficients into the quadratic formula.m=2⋅7−(−9)±(−9)2−4⋅7⋅2m=149±81−56
Simplify Discriminant: Simplify the expression under the square root (the discriminant).m=149±25m=149±5
Solve for Values: Solve for the two possible values of m.First solution:m=149+5m=1414m=1Second solution:m=149−5m=144m=72 after simplifying the fraction.
