Solve x2 − 7x + 12 = 0.
x = −3, x = −4
x = 3, x = 4
x = 2, x = 6
x = −2, x = −6

x=4, x=3

B is correct.

Step-by-step explanation:

Given:

Using middle term splitting factor the left side equation.

Equate each factor to 0 and solve for x

x-4=0    or     x-3=0

x=4 and x=3

Hence, The solution of the equation is 4 or 3

step-by-step explanation:

left be aligning the decimal points is required to not required see the number of digits to the right
