Find the roots of the quadratic equation: 3x2−5x+2=03x^2 - 5x + 2 = 0 using the quadratic formula.

Answer: The roots of the quadratic equation 3x2−5x+2=03x^2 - 5x + 2 = 0 are x=1x = 1 and x=23x = \frac{2}{3}.

Step-by-step solution

Step 1: Identify coefficients

First, we compare the given quadratic equation 3x2−5x+2=03x^2 - 5x + 2 = 0 with the standard form of a quadratic equation, ax2+bx+c=0ax^2 + bx + c = 0. This allows us to identify the coefficients aa, bb, and cc.

Step 2: Apply the quadratic formula

Next, we write down the quadratic formula, which is used to find the roots of any quadratic equation. This formula provides a direct way to calculate the values of xx.

Step 3: Substitute values into the formula

Now, we substitute the identified values of a=3a=3, b=−5b=-5, and c=2c=2 into the quadratic formula. This is the crucial step before performing the calculations.

Step 4: Simplify the expression

We simplify the expression under the square root and perform the multiplication in the denominator. The term b2−4acb^2 - 4ac is called the discriminant, and its value helps determine the nature of the roots.

Step 5: Calculate the roots

Finally, we calculate the two possible roots by considering both the positive and negative signs of the square root. This gives us the two solutions for xx.
