Write an algebraic expression for:
12lessthanthreetimesanumbersquared
Define our algebraic expression:
A math expression containing any of the following items:
- Constants (A numeric value that does not change like 5)
- Variables (A letter used to represent a quantity like x)
- Operations (Add (+), Subtract (-), Multiply (*), Divide (÷), Exponent (^), Equation (=))
Replace the word three with 3
12lessthan3timesanumbersquaredA Number means a random variable
We will call it x
Evaluate the phrase squared
Raise x to the power of 2
Evaluate the phrase Times
Multiply the term x2 by the constant 3
3x^{2}
Evaluate the phrase Less Than
Setup An Inequality On the term (3x2) with respect to the constant 12
12 < (3x^{2})
Final Answer
12 < (3x2)
