Answer 2

Answer:

x^2+3^3=31

We move all terms to the left:

x^2+3^3-(31)=0

determiningTheFunctionDomain

x^2-31+3^3=0

We add all the numbers together, and all the variables

x^2-4=0

a = 1; b = 0; c = -4;

Δ = b2-4ac

Δ = 02-4·1·(-4)

Δ = 16

The delta value is higher than zero, so the equation has two solutions

We use following formulas to calculate our solutions:

x1=−b−Δ√2ax2=−b+Δ√2a

Δ−−√=16−−√=4

x1=−b−Δ√2a=−(0)−42∗1=−42=−2

x2=−b+Δ√2a=−(0)+42∗1=42=2
