131x
Step-by-step explanation:
7x² + 6x + 9x² - 5x
49x + 6x + 81x - 5x
136x - 5x
131x
The simplification of the given equation is x(16x + 1).
Given that,
Based on the above information, the calculation is as follows:
[tex]= 7x^2 + 6x + 9x^2 - 5x\\\\= 16x^2 + 6x - 5x\\\\= 16x^2 +x\\\\= x(16x+ 1)[/tex]
