How much does 93p² - 55p + 4 exceed 13p³ - 5p² + 17p - 90
Solution:
The given expressions are 93p² - 55p + 4 and 13p³ - 5p² + 17p - 90.
We have to determine by how much does 93p² - 55p + 4 exceed 13p³ - 5p² + 17p - 90
Required expression = 93p² - 55p + 4 - (13p³ - 5p² + 17p - 90)
= 93p² - 55p + 4 - 13p³ + 5p² - 17p + 90
By combining like terms,
= 93p² + 5p² - 13p³ - 55p - 17p + 4 + 90
= (93 + 5)p² - 13p³ + (-55 - 17)p + (4 + 90)
= 98p² - 13p³ + (-72)p + 94
= -13p³ + 98p² - 72p + 94
Therefore, the required expression is -13p³ + 98p² - 72p + 94.
