i have 6 problems that I did and want to make sure I am correct?

Question

I need to see your work to make sure mine is accurate

1. Solve by factoring:
x2 – 13x = -12



2. Solve using the square root property:
2x2 – 35 = 15


3. Solve using the square root property:
(x + 6)2 = 4

4. Solve by completing the square:
x2 + 6x + 1 = 0


5. Solve using the quadratic formula:
x2 – 3x = 7x – 2

6. Solve using the quadratic formula:
x2 – 7x – 1 = -7

Answer 1

1 x=1 or x=12
2 x= +5 or x= -5
3. x-6 = +/-2
x =+/-2 +6
x=4 or x=8
4. x= -3 +/- 2 √2
5. x²-10x+2=0
x = 5 +/- √(25-2) = 5 +/- √23
6. x= [7 +/- √(49-24)]/2 =[7+/- 5]/2
x=1 or x=6

Answer 2

a convinced, 9.7 x 10^2 is ideal. widely used notation is one digit to the left of the decimal factor something of digits to the right of the decimal factor. observed through an "*" or a lowercase "x". it extremely is observed through the form 10. it extremely is then observed through the exponent mandatory to advance ten to the right capacity. b. multiply 6.8 cases 4.fifty 4. the effect is larger than 10 so that you should flow the decimal factor one position to the left to achieve widely used notation. that provides something cases 10^a million. Then we favor to consider the powers of ten contained in the unique challenge besides because the single basically created. Combining 10^3, 10^6 and 10^a million turns into 10^10 your answer will for this reason be something x 10^10 c. paintings this the picture of b.

Answer 3

1) x= 12 or x=1

2)A little unclear about this one, did you type it right?

3) x= -4

4) 3+sqrt(8) or 3+2sqrt(2)

5) -2 +- sqrt(2)

6)x=6 or x=1

Just to confirm...
