Answer:
Discriminant is 17 and it has 2 real roots.
Step-by-step explanation:
To find the number of real roots for a quadratic, we apply the discriminate. The discriminate is the inside portion of the square root from the quadratic formula.
• 
yields 2 real roots
• 
yields 1 real root
• [tx]b^2-4ac<0[/tex] yields no real roots
where a=4, b=-7, and c=2
.
It has 2 real roots
Answer: 1
Step-by-step explanation: Whenever you take the power of a power, the find the answer you can multiply the two exponents, for example:
(x^3)^4 = x^12
We will use that here.
a^8a^6 = a^14
((a^14)^1/7) = (a^2)/a^2
Our answer is 1
