There are two real solutions
Step-by-step explanation:
We have the following quadratic equation
a refers to the coefficient next to
b refers to the coefficient with
c refers to the number without x
This means that
We now can plug these variables into the discriminant formula
As our answer is positive, we can determine that this quadratic equation has two real solutions.
Ответ:
5(y - 3) - 2 (3 - 2y) = 6
5(3 - 3) - 2(3 - 2 × 3) = 6
The equation works!
Y = 3
Great work!
