Answer:

(0, - 3) and (4, 5)

Step-by-step explanation:

Given the 2 equations

y = x² - 2x - 3 → (1)

y = 2x - 3 → (2)

Substitute y = x² - 2x - 3 into (2)

x² - 2x - 3 = 2x - 3 ← subtract 2x - 3 from both sides

x² - 4x = 0 ← in standard form

x(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x = 0

x - 4 = 0 ⇒ x = 4

Substitute these values into (2) for corresponding values of y

x = 0 → y = 2(0) - 3 = 0 - 3 = - 3 ⇒ (0, - 3 )

x = 4 → y = 2(4) - 3 = 8 - 3 = 5 ⇒ (4, 5 )

Hello! Although I can't give you the answers automatically. I'll just show you some steps on how to subtract & if you're still not figuring it out just message me! :)

Step 1: You have to make sure both denominators are both exactly the same or you won't get the answer correctly.

Step 2: Then subtract the numerators

Step 3: Simplify if needed.

Ex; If I have 1/2 of the pizza and my friend has 1/6 of the pizza. What will be my result if I subtract the fractions?

We'll have to take 1/2 and 1/6. You'll have to find what makes those numbers, what I mean is by multiplying both numerators and denominators.

\frac{1}{2}  -  \frac{1}{6}  =
You multiply by 3.
2 x 3 = 6

Then you'll change the denominator into 1/2 = 1/6

Result:
\frac{3}{6}  -    \frac{1}{6}  =
Then you just subtract.
3 - 1 = 2

Hint: Denominator never changes when you have your final result. So it's 2/6. It needs to be simplified.

\frac{2}{6}  \div  \frac{1}{3}
We divide by 2.

I hope this example helped you understand how to subtract fractions & if you don't know how to add mixed fractions you can always do around the world or other examples your teacher can provide! :)

Describe the error made in subtracting the two rational expressions shown:
horrorfan [7]

Answer:

You must subtract all terms of the numerator being subtracted out, not just the first term.  The negative 2 should have been subtracted out to get a numerator of x + 1 - x + 2.  The simplified numerator of the difference should be 3, not –1.
