Answer:

x^2-8x-9

−8x−9

Step-by-step explanation:

You have to factor the expression in order to get your answer

Do this by expanding out the expression: (x-10)(x-10)

Then factor by multiplying each of the components! Use the FOIL acronym to help you. FOIL stands for First, Outer, Inner, Last. Meaning multiply the first numbers of the expressions together, then the outers, then the inner two numbers, then the last two numbers of the expression.

Multiply x and x to get , multiply x and -10 to get -10x, multiply -10 and x to get -10x, multiply -10 and -10 to get 100. Add them all together: . Then combine like terms

To evaluate the expression all you have to do is substitute the value for the variable.

3 + y + 6, y = 5
3 + 5 + 6
8 + 6
14.

The solution is 14.

How do I factor the quadratic equation

anastassius [24]

Factor the following:
10 y^2 - 35 y + 30
Factor 5 out of 10 y^2 - 35 y + 30:
5 (2 y^2 - 7 y + 6)
Factor the quadratic 2 y^2 - 7 y + 6.
The coefficient of y^2 is 2 and the constant term is 6.
The product of 2 and 6 is 12.
The factors of 12 which sum to -7 are -3 and -4. So 2 y^2 - 7 y + 6 = 2 y^2 - 4 y - 3 y + 6 = y (2 y - 3) - 2 (2 y - 3):
5 y (2 y - 3) - 2 (2 y - 3)
Factor 2 y - 3 from y (2 y - 3) - 2 (2 y - 3):
Answer: 5 (2 y - 3) (y - 2)

Now find another real world example (it can be a similar range problem). Graph it on a number line, and then explain the minimum

Kaylis [27]

The real world example for the absolute value are to express the change in balance of account.

How to use absolute value in real world problem?

Absolute value in real world problem is used to express the change or variation from one point to another point. In the absolute value, the sign of the number is not consideredd.

Let a real world example-

Everyone is going with 20 km/h and a person x is going with 15 km/h.
The person x has most likely to get the token as the difference between his speed and public speed is 5 km/h.
The sign of the number is not considered, whether it is +5 or -5 it is the difference of 5 km/h.
