Answer:
14
Step-by-step explanation:
Please be certain to use " ^ " to denote exponentiation:
3x^2 + 4x – 5, 7x^2 + x + 9, 4x^2 - 3x
First, perform this subtraction:
7x2 + x + 9
-(3x2 + 4x – 5)
-----------------------
4x^2 - 3x + 14
Next, subtract 4x^2 - 3x from the above result:
4x^2 - 3x + 14
-(4x^2 - 3x)
------------------------
14 (answer)
The value after difference is 14.
What is polynomial?
Polynomials are sums of terms of the form k⋅xⁿ, where k is any number and n is a positive integer.
Given polynomial; 3x² + 4x – 5, 7x² + x + 9 and 4x² - 3x
First, subtraction is 7x² + x + 9 -(3x² + 4x – 5) :
7x² + x + 9 -(3x² + 4x – 5)
= 7x² + x + 9 -3x² - 4x + 5
= 7x² -3x² + x - 4x + 9 + 5
= 4x²-3x+14
Next, subtract 4x² - 3x from the above result:
4x²-3x+14 - (4x² - 3x)
= 4x²-3x+14- 4x² + 3x
=14.
