The correct answer for b^2 - 4ac (also known as the discriminant) should be 57 or answer C.

You first must solve the equation for 0.
<span>1 = 2x2<span> + 7x ---> subtract 1 from each side
</span></span>0 = 2x^2 + 7x - 1

Now we can find a as the coefficient of the x^2 term, b as the coefficient for the x term an c as the number at the end.
a = 2
b = 7
c = -1

Now we can plug these values in for b^2 - 4ac

b^2 -4ac
(7)^2 - 4(2)(-1)
49 + 8
57

Hey there!

<h2>ANSWER: </h2>

Non linear

<h2>EXPLANATION:</h2>

Is $2^x=8$ linear or non-linear.

Since x has an exponent value that is equal to 2, it's non-linear. So that means $2^x=8$ is non-linear.

Hope this helps!
