Solving Quadratic Equations
The general form of a quadratic equation is:
It can be solved by using the formula:
we have the following equation:
we need to put this equation in standard form as explained above
Adding 2x^2:
Now we have the equation in the correct form, we find the value of the variables as follows:
a=1, b=-7, c=7
Applying the formula:
Operating:
The square root of 21 is not exact, we use two decimals so far, and we'll round to one decimal at the very last time.
Taking the square root:
The solutions (to the nearest tenth) are:
x= 7.8
x=1.2
