Answer:

x² - 2x - 15 = 0

Step-by-step explanation:

Given that the roots are x = - 3 and x = 5

Then the factors are (x + 3) and (x - 5)

The equation is then the product of the factors

(x + 3)(x - 5) = 0 ← expand left side using FOIL

x² - 5x + 3x - 15 = 0, that is

x² - 2x - 15 = 0

Answer:

I have attached a picture of me solving the equation.

Now you must be wondering how I got the answer, well first simplify the expression in y = mx + b. Then graph it on demos. Do the same thing for the other expression. Pick any point that lies on the line. That is your solution to the equation.

The green line is the expression of 3x - 4y = 11. I simplify the equation in y = mx + b giving me y = 3/4x - 11/4.

The orange line is the expression of 3x + 2y = 2. I simplify the equation in y = mx + b giving me y = -3/2x + 1.

Hope this helps, thank you !!

Can someone help me with this question

maria [59]

Step-by-step explanation:

1/5 + 3/5 = 3/5 + 1/5 = 4/5

I am not sure what your teacher wants to see on the right side of the second equation.

it would be the whole equation again :

4/5 = 1/5 + 3/5 = 3/5 + 1/5
