Question from Sonjonnia, a student: What is the value of the discriminate? |
Sonjonnia,
The first think I notice is that 4 divides both sides of the equation. Dividing both sides by 4 gives
4x2 = 4x - 1.
To find the value of the discriminant you need to write the quadratic in standard form ax2 + bx + c.
Once you have done that the discriminant is given by b2 - 4ac.
I hope this helps,
Penny
