Q. Solve using the quadratic formula.6x2−7x+2=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.x=_____ or x=_____
Quadratic Formula: The quadratic formula is given by x=2a−b±b2−4ac, where a, b, and c are the coefficients of the quadratic equationax2+bx+c=0. In this case, a=6, b=−7, and c=2.
Calculate Discriminant: First, calculate the discriminant, which is the part under the square root in the quadratic formula: b2−4ac. Discriminant = (−7)2−4(6)(2)=49−48=1.
Apply Quadratic Formula: Since the discriminant is positive, there will be two real solutions. Now, apply the quadratic formula to find the two values of x.x=2×6−(−7)±1.
Solve for x (Positive): Simplify the equation by calculating the numerator for both the positive and negative square root cases.x=127±1.
Solve for x (Negative): Now, solve for x using the positive square root: x=127+1=128.Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 4.x=32.
Solve for x (Negative): Now, solve for x using the positive square root:x=127+1=128.Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 4.x=32.Next, solve for x using the negative square root:x=127−1=126.Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 6.x=21.
