Question

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

Answer 1

Answer:

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

Step-by-step 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;

$b^2-4ac = 8^2-4\times3\times1$

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

so we get;

$b^2-4ac = 64-4\times3\times1$

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 $b^2-4ac = 52$.
