I got a couple I want to check my work :

Both are Solve using the quadratic formula :
1) x^2-3x=7x-2
x^2-3x-7x+2=7x-7x-2+2
x^2-10x+2=0
x = 10 +- sqrt10^2 - 4(1)(2) / 2(1)
x = 10 +- sqrt100 - 8 / 2
x = 10 +- sqrt92 / 2
x = 10 +- 2sqrt23 /2
x = 5 +- sqrt23
x = 5 + sqrt23 and x = 5 - sqrt23

2) x^2-7x-1= -7
x^2-7x+7-1 = -7+7
x^2-7x+6 = 0
x = 7 +- sqrt7^2 - 4(1)(6) / 2(1)
x = 7 +- sqrt49-24 / 2
x = 7 +- sqrt25 / 2
x = 7 +- 5 / 2
x = 7+5 / 2 , x = 12 / 2 , x = 6
x = 7-5 / 2 , x = 2 / 2 , x = 1

The second one looks ok. I think step 7 of problem 1 has an error.

Ok so what I did was

x = 10 +- 2sqrt23 / 2
I divided 10 by 2 and 2 by 2
Thats how i got
x = 5 +- sqrt23

1) x^2-3x=7x-2

x^2-3x-7x+2=7x-7x-2+2
x^2-10x+2=0
x = 10 +- sqrt10^2 - 4(1)(2) / 2(1)
x = 10 +- sqrt100 - 8 / 2
x = 10 +- sqrt92 / 2 OK to here. See below.

x = 10 +- 2sqrt23 /2
x = 5 +- sqrt23
x = 5 + sqrt23 and x = 5 - sqrt23

x = (10+-sqrt 92)/2
x = (10+-sqrt 2(46)/2
(What you are doing here is dividing 10 by 2, which is correct, as well as 2/2, which also is correct. What is NOT correct is dividing 46 by 2 (you are using the divisor of 2 twice but the divisor of 2 disappeared when you used it to divide the 10 and 2 of 2*46).
x = (5+-sqrt 46)

7x-2=22.5

Let's verify your work for both problems and see if your solutions are correct.

1) x^2 - 3x = 7x - 2

First, simplify the equation:
x^2 - 3x - 7x + 2 = 0
x^2 - 10x + 2 = 0

Now, we can use the quadratic formula to solve for x:
x = (-b ± √(b^2 - 4ac)) / (2a)

Plug in the values of a, b, and c from the quadratic equation:
x = (-(-10) ± √((-10)^2 - 4(1)(2))) / (2(1))
x = (10 ± √(100 - 8)) / 2
x = (10 ± √92) / 2
x = (10 ± 2√23) / 2
x = 5 ± √23

So the correct solutions are x = 5 + √23 and x = 5 - √23.

Your solution is correct!

2) x^2 - 7x - 1 = -7

First, simplify the equation:
x^2 - 7x + 7 - 1 = 0
x^2 - 7x + 6 = 0

Now, we can use the quadratic formula to solve for x:
x = (-b ± √(b^2 - 4ac)) / (2a)

Plug in the values of a, b, and c from the quadratic equation:
x = (-(-7) ± √((-7)^2 - 4(1)(6))) / (2(1))
x = (7 ± √(49 - 24)) / 2
x = (7 ± √25) / 2
x = (7 ± 5) / 2
x = (7 + 5) / 2 , x = (7 - 5) / 2
x = 12 / 2 , x = 2 / 2
x = 6 , x = 1

So the correct solutions are x = 6 and x = 1.

Your solution is correct!

Good job on solving these quadratic equations using the quadratic formula!
