Find the value of the greater root of x^2 - 13x + 12 = 0.

a) -12

b) -1

c) 1

d) 12

The largest root of this equation is 12

Step-by-step explanation:

To find this, first factor the equation.

x^2 - 13x + 12 = 0

(x - 12)(x - 1) = 0

Now set each parenthesis equal to 0 to get the roots.

x - 12 = 0

x = 12

x - 1 = 0

x = 1

The larger of those two is 12 and that is the answer.
