Question

B^2+ 4ac solutions - any solution with this problem will help me to figure out this formula- class-X​

Answer 1

Answer:

Step-by-step explanation:

2x2 + 5x + 3 = 0 In this one a=2, b=5 and c=3

x2 − 3x = 0 This one is a little more tricky:

Where is a? Well a=1, as we don't usually write "1x2"

b = −3

And where is c? Well c=0, so is not shown.

5x − 3 = 0 Oops! This one is not a quadratic equation: it is missing x2

(in other words a=0, which means it can't be quadratic)
