Question 109499
Solve using the quadratic formula:
x2 – 3x = 7x – 2
x^2-10x+2 = 0
x = [10 +- sqrt(100-4*2)]/2
x = [10 +- sqrt(92)]/2
x = [10 +- 2sqrt(23)]/2
x = 5 + sqrt23 or x = 5 - sqrt23
============== 

x2 – 7x – 1 = -7 
x^2-7x+6 = 0
x = [7 +- sqrt(49-4*6)]/2
x = [7 +- sqrt(25)]/2
x = [7 +- 5]/2
x = 6 or x = 1
=================
