Question

Hello, id like to know what
`(4 {x}^(2) + 6) - (2x - 5)`equals to

Answer 1

When two binomials are joined by the subtraction operation, we just need to combine similar terms. See the steps below.

1. Eliminate the parenthesis and make sure to distribute the negative symbol outside the second parenthesis to the terms inside the second parenthesis.

`4x^2+6-2x+5`

2. Rearrange the terms according to the degree of their exponents.

`4x^2-2x+6+5`

3. Combine similar terms. The only similar terms above are +6 and +5. When combined, the result is +11. Hence, the answer is:

`4x^2-2x+11`

Answer:

4x² - 2x + 11
