Which polynomial is in standard form? 1+ 2x-8x^2+6x^3
2x^2 +6x^3-9x+ 12
6x^3+ 5x-3x^2+2
2x^3+4x2 - 7x+5

2x^3 + 4x^2 - 7x + 5

Step-by-step explanation:

Start your hunt by looking for the polynomials in which the highest power of x comes first.  That automatically eliminates the first two answer choices.

In which of the remaining two polynomials do the powers of x appear in descending order?  Not in 6x^3+ 5x-3x^2+2.  Therefore, the correct answer is the fourth:  2x^3 + 4x^2 - 7x + 5.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2
