(5x+1)² = 7; expand: 25x² + 10x +1 = 7 or 25x² + 10x -6 = 0

Solve this quadratic for x:

x = [-b + √(b² - 4ac)]/2a and x = [-b - √(b² - 4ac)]/2a
Plug the values and you'll find :
x = (- √7 - 1)/5 (answer C)
x = (+√7 -1)/5  (answer E)

Put the steps in order to show how to solve the equation 4y - 7 = 25
kumpel [21]

Answer:  E, A, D, C, B

Step-by-step explanation:

First, we need to get y alone. So we will add 7 to the side of the equation that has the 4y in it.

So the first one will be.

<em><u>Add 7 to both sides of the equation.</u></em>

Now the second one is

<em><u>4y = 25 + 7  </u></em>Because what you do to one side of the equation, you do to the other. So we add 7 to 25.

Then the 3rd one will be <u><em>4y = 32  </em></u>because 25+7 is equal to 32. But we still have that 4y on the other side of the equation. So the next equation is 4y = 32.

The second to last step is <em><u>Divide both sides by 4  </u></em>because thats

how you isolate y. So once you divide both sides by 4. You will get 8. Leading you into the next and final step.

<em><u>Y = 8</u></em>

And thats how you do it!
