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
