Evaluate y=x squared minus 2x plus one for 3i

pychu [463]

Answer:

$- 8 - 6i$

Step-by-step explanation:

The given expresion is

$y = {x}^{2} - 2x + 1$

We want to evaluate this expression when x=3i

We substitute to obtain:

$y = {(3i)}^{2} - 2(3i) + 1$

We simplify to get

$y = {3}^{2} \times {i}^{2} - 6i + 1$

Recall that

${i}^{2} = - 1$

This implies that:

$y = 9 \times - 1 - 6i + 1$

$y = - 9 - 6i + 1$

$y = - 8 - 6i$

A teacher wrote the following set of numbers on

Rama09 [41]

Answer:

Did you copy this down correctly?

Step-by-step explanation:

b = .125 which is rational

a is irrational because the square root of a prime number is irrational.

If c = 225....

then adding 2 rational numbers = rational sum

But adding (or multiplying) an irrational number to a rational number = irrational number.

Find a number whose product with 9 is the same as its sum with 56

eimsori [14]

Let x be that number.
9x must be the same as x+56:
$9x = x+56$ .
We substruct x from both sides:
$8x = 56$
and we divide by 8 in both sides of the equality:
$x = 7$
