Step-by-step explanation:
2 < x < 4 and 3 < y < 7
We have (2 + 3) < (x + y) < (4 + 7),
Therefore 5 < x + y < 11.
The largest integer value for
x + y is 10.

Sorry though i dont know how to speak Spanish
Let's find the discriminant of <span>x^2+9x+14=0. Here, a=1, b=9 and c=14.
The discriminant is b^2-4ac. Substituting the above numeric values,
9^2-4(1)(14) = 81-56 = 25
The sqrt of 25 is 5. Thus, your polynomial has two unequal, real roots.
Off the point example: If the discriminant were zero, your poly would have two real, equal roots.</span>
