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
Thanks
Let me try again...
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.
