x + 5 and 4x^2
Multiply the exponent of x by 2giving
The answer is
x^2 evaluates to
Multiply a and 5
Multiply a and 1
The a just gets copied along.
The answer is a
a
5*a evaluates to 5a
Answer:
Step-by-step explanation:
The discriminant of a quadratic equation is b² - 4ac.
Here, a = 1, b = 3 and c = 8, and so the value of the discriminant is:
3² - 4(1)(8) = 9 - 32 = -23
The discriminant is -23 in this case.
A negative discriminant indicates that the roots will be complex.
