Answer :
Because this expression can actually be written as x (4x-10)(4x-10)(4×-10)
x and 4x - 10 are a factor of the expression x(4x-10)³ because they are in the multiplication form of the equation.
What is expansion?
Expanded form is the term used in mathematics to refer to the process of expanding a number to convey the value of every digit and place value.
When a mathematical object is increased by a multiplier that is bigger in actual values than one, an expansion follows.
In another word, if you solve a factor by opening the bracket then you will go to get on some expanded term called expansion.
In mathematics, all real-life problems can be converted into equations which are sometimes in form of factors and we need to expand them to create solutions.
Given the expression x(4x-10)³
If we expand it then it will be
x(4x-10)(4x-10)(4x-10)
And factors are nothing but the multiplication of terms.
Factor also gives us the value of roots.
