Solve for x: 2x2−7x+3=02x^2 - 7x + 3 = 0. I am a class 10 student, please help me understand how to do it.

Answer: The solutions for xx are 33 and 12\frac{1}{2}.

Step-by-step solution

Step 1: Identify coefficients

The given equation is 2x2−7x+3=02x^2 - 7x + 3 = 0. This is a quadratic equation in the standard form ax2+bx+c=0ax^2 + bx + c = 0. By comparing the given equation with the standard form, we can identify the coefficients aa, bb, and cc.

Step 2: Apply the quadratic formula

Now that we have the values of aa, bb, and cc, we can use the quadratic formula to find the values of xx. The quadratic formula provides the solutions for any quadratic equation.

Step 3: Substitute values into the formula

Substitute the identified values a=2a = 2, b=−7b = -7, and c=3c = 3 into the quadratic formula. Be careful with the signs, especially for the term −b-b.

Step 4: Simplify the expression

First, calculate the term inside the square root, which is the discriminant b2−4acb^2 - 4ac. Then, simplify the square root and the denominator.

Step 5: Calculate the two possible values for x

The ±\pm sign in the quadratic formula indicates that there are two possible solutions for xx. Calculate each solution separately, one using the plus sign and the other using the minus sign.

Step 6: Final solutions

Perform the final division for both expressions to get the two solutions for xx. These are the roots of the quadratic equation.
