Multiply (2 - 71)(-1 + 41)?<br> 26 + 151<br> -2 - 281<br> 26 + i<br> -30 + 151
Ivahew [28]

For this case we must simplify the following expression:

(2-7i) (- 1 + 4i)

Applying distributive property we have:

(2) (- 1) + (2) (4i) + (- 7i) (- 1) + (- 7i) (4i) =

We have to:

+ * - = -\\- * - = +

So:

-2 + 8i + 7i-28i ^ 2 =

We add similar terms:

-2 + 15i-28i ^ 2 =

By definition we have:i ^ 2 = -1

-2 + 15i-28 (-1) =\\-2 + 15i + 28 =

Different signs are subtracted and the sign of the major is placed:

26 + 15i

Answer:

26 + 15i

Can someone give me the answer and how you work this? -5 - (-10) = ?
erastovalidia [21]

Answer:

5

Step-by-step explanation:

-5 - (-10)

Here we have to use sign of multiplication rule.

negative * negative = positive

that is, -(-) = +

We use this rule and simplify.

- (-10) = + 10

Therefore, -5 + 10

When we have different sign of the numbers, we have to subtract from greatest to least number, then put the largest number sign in the answer.

-5 + 10 = + 5

Hence, the answer is 5

Hope this is will help you.

Thank you.
