What is the least value of x that satisfies the equation x2 – 7x + 6 = 6 ?
F. -7
G. -6
H. -4
J. 0
K. 1
The correct answer is J.
Explanation:
x2 - 7x + 6 = 6, so x2 - 7x = 0, x(x - 7) = 0, so x = 0 or x = 7.
To check, if x = 0, 0 - 0 + 6 = 6. If x = 7, 72 - 7(7) + 6 = 6.
So 0 and 7 both satisfy x2 - 7x + 6 = 6 and the lesser of the two values is 0.
