Answer:

After evaluating we get
b^2-4ac = 52.

Explanation:

Given:


b^2-4ac

We need to evaluate the expression with a =3, b =8 and c= 1

Solution:

To evaluate the expression we will first substitute the values of a,b and c in the expression we get;


b^2-4ac = 8^2-4*3*1

Now by using PEDMAS which states first operation needs to perform here is the exponent function.

so we get;


b^2-4ac = 64-4*3*1

Now next operation to be performed is multiplication.


b^2-4ac = 64-12

And finally we will perform subtraction operation.


b^2-4ac = 52

Hence After evaluating we get
b^2-4ac = 52.
