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>
Answer: A) -8
B) - 41
C) - 39
Step-by-step explanation:
4 x 2 tens = 80, 28 x 14 = 392
Let x equal a number
3x + 5 = 26
3x = 21
x = 7
the number is 7!
