Question

Simplify the sum. (2u^3 + 6u^2 + 3) + (2u^3 - 7u + 6)

Answer 1

Steps:

1) Group the like terms and simplify.

2) Do follow the BODMAS Rule. Simplify terms inside the brackets, first. Then, follow this serial: Division, Multiplication, Addition, Subtraction.

Method:


`(2u^3 + 6u^2 + 3) + (2u^3 - 7u + 6)`

=
`2u^3 + 6u^2 + 3 + 2u^3 - 7u + 6`

=
`2u^3+2u^3+6u^2-7u+3+6`

=
`(2u^3+2u^3)+6u^2-7u+(3+6)`

=
`4u^3+6u^2-7u+9`
