The quadratic formula is
.
From the problem, a is 1, b is -1, and c is 12. Plugging in these values gives:

Because there is a square root of a negative number, there is no solution.
It isn’t because when there is no addition in the equation the y intercept is 0
Answer:
y= 8
Step-by-step explanation:
In a Triangle we know,
W+Y+X=180 degree
then,
(180-52)+(4y-4)+3y=180
or, 128+4y-4+3y= 180
or, 7y= 180- 124
or, y= 56/7
or, y= 8
hope you got it.
