Remember to follow PEMDAS and the left -> right rule.

<u>PEMDAS:</u>

Parenthesis

Exponent (& roots)

Multiplication

Division

Addition

Subtraction

----------------

Also, note the rules of sign:

Multiplying...

Positive number and another positive number will result in a positive answer.

Positive number and a negative number will result in a negative answer.

Negative number and another negative number will result in a <em>positive </em>answer.

--------------------------------------------------------------------------------------------------------

Note the question:

5 x -6 + (-7)

First, change the sign for -6 + -7. Note the rule above and change the sign.

5 x -6 - 7

Next, solve. Remember to follow PEMDAS. Multiply 5 and -6 together

5 x -6 = -30

Then, combine the remaining terms.

-30 - 7 = -37

You're answer:

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number? x = –1 and x =
andrey2020 [161]

we have

f(x)=x^{2}-2x-3

Find the roots

Equate the function to zero

x^{2}-2x-3=0

Group terms that contain the same variable, and move the constant to the opposite side of the equation

x^{2}-2x=3

Complete the square. Remember to balance the equation by adding the same constants to each side.

x^{2}-2x+1=3+1

x^{2}-2x+1=4

Rewrite as perfect squares

(x-1)^{2}=4

Square root both sides

(x-1)=(+/-)2

x=1(+/-)2

x=1+2=3

x=1-2=-1

therefore

<u>the answer is</u>

x=3
