<em><u>^2 = SQUARED( to the second power)</u></em>

Answer:

2. 2x times 2x equals 4x^2 since x times x equals x^2(and 2 times 2 equals 4. then positive i times negative i equals -i^2 which can transfer to be 1.

Step-by-step explanation:

2. 2x * 2x = 4x^2

   +i * -i = -i^2

   -i^2 can be transferred into positive 1.

   i is a variable. if you divide -i^2 by -i, then that equals i, which is 1.

3. The same thing as 2.^

   1 squared is 1. i squared is i^2. i^2 divided by i is i. i is 1. 1+1 is 2. Now put the 2 infront of the i to make 2i.

What is the distance between the solutions to the quadratic<br> equation x2 – 7x + 10 = 28
Kryger [21]

Answer:

11

Step-by-step explanation:

Given

x² - 7x + 10 = 28 ( subtract 28 from both sides )

x² - 7x - 18 = 0 ← in standard form

(x - 9)(x + 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 9 = 0 ⇒ x = 9

x + 2 = 0 ⇒ x = - 2

The distance between the solutions is

| 9 - (- 2) | = | 11  = 11 units
