2. Write 7x2 - 4 + 6x3 - 4x - x4 in standard form.

The expression 7x² - 4 + 6x³ - 4x - x⁴ written in standard form is -x⁴ + 6x³ + 7x² - 4x - 4

Standard form format:

ax² + bx + c

ax² + bx + cAx + by = c

In this case, the standard form format follows degree of power (from the highest degree to the lowest degree)

7x² - 4 + 6x³ - 4x - x⁴

From highest degree to lowest degree

= -x⁴ + 6x³ + 7x² - 4x - 4

Therefore, the expression 7x² - 4 + 6x³ - 4x - x⁴ written in standard form is -x⁴ + 6x³ + 7x² - 4x - 4
