Answer:
<u>The correct answer is B. {-2,4}</u>
Step-by-step explanation:
Let's solve for x, this way:
x + 4/4 = x /x -2
(x + 4) * ((x - 2) = 4 * x
x² - 2x + 4x -8 = 4x
x² - 2x + 4x -8 - 4x = 0
x² - 2x -8 = 0
(x - 4) * (x +2) = 0
x - 4 = 0
x + 2 = 0
x₁ = 4
x₂ = - 2
<u>The correct answer is B. {-2,4}</u>
Answer:5w^2 -2205
Step-by-step explanation:
simplify the product so (1) w mutiplied by w gives you w^2 . (2) 21 mutilplied by 21 gives you 441 . so now you would have 5( w^2 -441 ) (3) now you distribute 5 among the numbers so you should have 5w^2 -2205 .
Answer:
<em>Standard Form; x^2 - 11x + 24 = 0</em>
Step-by-step explanation:
Simplify rewrite such that the quadratic equation has 0 isolated on the right or left side, most commonly right side;
x^2 - 11x + 19 = - 5 ⇒ Add 5 on either side of equation,
<em>Standard Form; x^2 - 11x + 24 = 0</em>
So we are finding the difference btween 5x-3 and 3x+1.
(5x-3)-(3x+1)
Let's subtract the x's first.
5x-3x=2x
Now the numbers.
-3-1=-4
Now, we need to put 2x and -4 together.
The expression would be 2x-4.
