Answer:
i know do you speak ENGLISH
Step-by-step explanation:
First go to THE UNITED STATES
The number of solutions of a quadratic equation
ax^2+bx+c=0
Depends on its discriminant
/Delta=b^2-4ac
If /Delta>0 there are two distinct solutions
If /Delta=0 there are two coincident solutions
If /Delta<0 there are no solutions.
We know that there are two real solutions (I assume you mean distinct solutions), so we know that the discriminant is positive:
The number of solutions of a quadratic equation

If there are two distinct solutions
If there are two coincident solutions
If there are no solutions.
We know that there are two real solutions (I assume you mean distinct solutions), so we know that the discriminant is positive:
b^2-4ac=9+28t>0\iff t>-\dfrac[9][28]
The correct answer is:
A- 3•12+b
Sum means addition
To compare you should make the down part equal first
27/45 < 30/45
The coefficient of x^2 is positive so it will have a minimum value
Its B
