Answer:
Joshua has 2a^2 -6a + 7 more than Maranda.
Step-by-step explanation:
Joshua has 6a^2 -5a + 10 dollars and Maranda has 4a^2 + a + 3 to find out how much more money Joshua has we need to subtract the amount he has by the amount of Maranda's account. Since both expressions are pollynomial we'll have to subtract the numbers wich are multiplying the same power, so we do as follow:
6a^2 - 5a + 10 - (4a^2 + a + 3)
6a^2 - 5a + 10 - 4a^2 -a -3
6a^2 - 4a^2 -5a -a + 10 -3
2a^2 -6a + 7
Joshua has 2a^2 -6a + 7 more than Maranda.
