Respuesta :
You subtract the like terms, don't forget to distribute the subtraction sign, its 7x2+5x
Answer:
(A)[tex]7x^2+5x[/tex]
Step-by-step explanation:
Given:The given expression is:
[tex](9x^2+8x)-(2x^2+3x)[/tex]
To find: The difference of the two polynomials.
Solution: The given expression is:
[tex](9x^2+8x)-(2x^2+3x)[/tex]
Upon solving the above equation, we get
[tex]9x^2+8x-2x^2-3x[/tex]
Combining the like terms and then solving,
[tex]9x^2-2x^2+8x-3x[/tex]
[tex]7x^2+5x[/tex]
which is the required difference.
Hence, option A is correct.
