Please help me with some problems. Thank you!

Solve the equation by square root property.

3. 2x^2 = 26 I don't understand how to solve this problem.

Solve the equation using the quadratic formula.

7. 7x^2=-8x -2 This is what I got x= -8 -or+ square root -8/14

8. 16x^2+1=5x This is what I got x= 5 +or- square root of -39/32

3. divide each side by 2 and then take the square root of both sides

7. a = 7
b = 8
c = 2

8. a = 16
b = -5
c = 1
