MsSue can you tellme that whilesolving this question by sqarring what answer do you get
6x(^2)-x-1=0
Of course! I'd be happy to help you with quadratic equations. A quadratic equation is an equation of the form ax^2 + bx + c = 0, where a, b, and c are constants.
To solve a quadratic equation, you can use the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / (2a)
Let's work through an example:
Example: Solve the quadratic equation 2x^2 - 5x + 3 = 0.
Step 1: Identify the values of a, b, and c.
In this equation, a = 2, b = -5, and c = 3.
Step 2: Substitute the values into the quadratic formula.
x = (-(-5) ± √((-5)^2 - 4(2)(3))) / (2(2))
Simplifying further:
x = (5 ± √(25 - 24)) / 4
x = (5 ± √1) / 4
x = (5 ± 1) / 4
Step 3: Simplify the expression.
x = (5 + 1) / 4 or x = (5 - 1) / 4
x = 6 / 4 or x = 4 / 4
x = 3 / 2 or x = 1
So, the solutions to the quadratic equation 2x^2 - 5x + 3 = 0 are x = 3/2 and x = 1.
Remember, the quadratic formula can be used to solve any quadratic equation, regardless of the values of a, b, and c.
