Here we are given with a equation:
And we have to solve it with appropriate steps.
So, let's start solving.
Add 2197 to both sides of the equation,
Now, using the identity:
a³ + b³ = (a + b)(a² - ab + b²)Let's proceed further.
x³ is the cube of x and 2197 is the cube of 13
Now,
x + 13 = 0x² - 13x + 13 = 0So, x = -13
And, for the second let's use the discriminate formula,
➝ D = b² - 4ac
➝ D = (-13)² - 4(1)(13)
➝ D = 169 - 52
➝ D = 117
Now, using the D. formula,
So the roots of the equation are:
And we are done !!

You must have wrote the equation incorrectly
Step-by-step explanation:
You wanna make f(x) equal to 6
So its 6 = 2x + 57
Subtract 57 from both sides to get -51 = 2x
Divide both sides by 2 to get -25.5
