Can anyone solve the following quadratic equation using the formula method...
Xsquared - 10x + 3 = 0
Please show working out so it is possible for me to follow and see where i am going wrong
It seems he's allowed to use the quadratic formula.
All quadratic equations are written in the format of
That means that is the co-efficient of the ; is the co-efficient of ; and is the constant.
According to the quadratic formula:
All you have to do is substitute the corresponding co-efficients into the formula.
A standard quadratic equation is in the form
a, b and c being the coefficients.
The formula for the discriminant ( ) is
If , there are 2 different roots.
If , there are 2 equivalent roots. ( )
If , there are no real roots.
The roots are,
Now plug a, b and c in these formulas.
