Answer:

4x^2+8x-5

Step-by-step explanation:

You work backwards to get (2x-1) which gets you the root 1/2 and (2x+5) which gets you the root -5/2 after this you foil what you have so (2x-1) times (2x+5). You do 2x times 2x which gives you 4x^2 2x times 5 which gives you 10x -1 times 2x which gives -2x and lastly -1 times 5 which gives you -5 now you combine like terms and get your final answer of 4x^2+8x-5

answer: 6.4

work:

Solve the problem.

Let's start by solving the numerator,

(5 + 3)² <em>step one: add 5 + 3 </em>

(8)² <em>step two: simplify 8²</em>

64

now, let's simplify our denominator

1 + 2⁵ - 23 <em>step one: simplify 2⁵.</em>

1 + 32 - 23 <em>step two: add 1 + 32.</em>

33 - 23 <em>step three: subtract 33 - 23</em>

10.

now, put the numerator back over the denominator.

64/10

let's simplify by dividing, we get 6.4.
