Find the value of the lesser root of x2 - 7x + 12 = 0.
a) -3
b) -1
c) 1
d) 3

So then since we want the lesser root the correct answer on this case is:

D) 3

Step-by-step explanation:

For this case we have the followin expression:

For this case we can use the quadratic formula in order to solve it, given by:

And on this case a = 1, b = -7, c = 12. And if we replace we got:

So then since we want the lesser root the correct answer on this case is:

D) 3
