Answer:

Step-by-step explanation:
For example, we'll use this quadratic equation.

To understand how to plug it into the formula we need to know what each term represents.

So the equation above would be put into the formula like this.

Then we would solve

Now, the equation will branch off into one that solves when addition and one when subtraction.

So x={-3, -2} (-3 and -2)
56 miles, The car traveled m miles during the first hour and m squared miles during the second hour. The ratio m/m squared = 1/7 and cross multiplying yields m squared = 7m, so m=7. This means that the total distance traveled was 7+7squared = 56 miles

Step-by-step explanation:
(1 + ax)⁴(2 - x)³ = (1 + 2ax + a²x²)²(8 - 12x + 6x² - x³) =
(1 + 4a²x² + a⁴x⁴ + 4ax + 2a²x² + 4a³x³)(8 - 12x + 6x² - x³) = ... 6x² + 32a²x² - 48ax² + 16ax² ...
= ... x²(6 + 32a² - 32a) ...
32a² - 32a + 6 = 6
32a(a - 1) = 0 → 32a = 0 → a = 0 OR a - 1 = 0 → a = 1
