Answer:
D. {1, 12}
Step-by-step explanation:
4X^2-52x+169=121
The equation can be summarized thus:
4X^2-52x+169-121=0
4X^2-52x+48=0
divide the each number of the equation by 4
4X^2/4-52x/4+48/4=0
x^2-13x+12=0
we need to numbers that when we multiply them the result is 12 and -13 when we add together
-1 and -12(-1-12=-13 and -1*-12=12)
x^2-x-12x+12
x(x-1)-12(x-1)
(x-1)(x-12)
x-1=0 or x-12=0
x=1 or x=12
