Question

Evaluate the expression when a=3,b=8, and c=1
B^2-4ac=

Answer 1

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`.
