Answer:
Below in BOLD.
Step-by-step explanation:
1. The discriminant D = b^2 - 4ac
= 3^2 - 4*5*(-7)
= 9 + 140
= 149.
Positive value so it has 2 real solutions.
2. D = (-12)^2 - 4 * 9 * 4
= 144 - 144
= 0.
So it has one real solution.
3. D = 2^2 - 4*1*3
= -8.
It is negative so there are No real solutions.
4. D = 4^2 - 4*2*10 = 16 - 80 = -64.
No solutions.
5. D = (-12)^2 - 4*3*(12)
= 144 - 144 = 0
So its the second choice.

Answer:
Step-by-step explanation:
p^8 q^6 / p ^4 q^3
In this expression the base of numerator and denominator is same:
We will change the division into multiplication and the denominator will become numerator will negative exponents:
p^8 q^6 * p ^-4 q^-3
Now simplify the terms with same base
The exponents of the same base will be added
=p^8+(-4) q^6+(-3)
=p^8-4 q^6-3
=p^4 q^3
The answer is p^4 q^3....
