a student's solution to the equation x/4 +6=2 is shown. She made a mistake while solving the problem . What is the correct answer shown below?

2

Step-by-step explanation:

multiply 4 on both sides first

4 times 2 = 8

x + 6 = 8

subtract 6 from both sides

x = 2

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

answer: i think one of the answer is $150 and $300?
