Question

9.Find the zeroes of 9x
^3 – 36x .
CLASS 10 POLYNOMIAL​

Answer 1

Step-by-step explanation:

Okay, so the equation is 9x³ - 36x and we have to find the roots of x.

So it's not a well defined question as we aren't given what it's equal to but in general case we'll take it equal to 0.

So the equation becomes

9x³ - 36x = 0

9x(x² - 4) = 0 {The common is 9x so we take it out}

x² - 4 = 0 {If we take 9x to the RHS it becomes 0}

x² = 4 {Shifting 4 to RHS}

x = √4 {Shifting square to RHS}

x = ±2 {√4 is ±2}

So, the value of x is either +2 or -2.

Mind that if it's a distance question take positive value always :)
