You use the discriminant of the quadratic formula which is
Using the values of the given quadratic formula you will find that
If the discriminant equals less than 0 you have no real roots(imaginary roots).
If it equals exactly 0, you have 2 real equal roots.
If it is more than 0, then you have two different real roots.
Therefore the quadratic function
Will have two real roots.
Answer:
the second option 2a-6b+c
Step-by-step explanation:
12+4.3-15
16.3-15
1.3
as you can see you have to use commutative property given !!!!!!!!!
X+3=61
x=61-3=58
58+37=95
180-95=85
so x=58 and y=85
