Answer:
p²q³ + pq and pq(pq² + 1)
Step-by-step explanation:
Given
3p²q² - 3p²q³ +4p²q³ -3p²q² + pq
Required
Collect like terms
We start by rewriting the expression
3p²q² - 3p²q³ +4p²q³ -3p²q² + pq
Collect like terms
3p²q² -3p²q² - 3p²q³ +4p²q³ + pq
Group like terms
(3p²q² -3p²q²) - (3p²q³ - 4p²q³ ) + pq
Perform arithmetic operations on like terms
(0) - (-p²q³) + pq
- (-p²q³) + pq
Open bracket
p²q³ + pq
The answer can be further simplified
Factorize p²q³ + pq
pq(pq² + 1)
Hence, 3p²q² - 3p²q³ +4p²q³ -3p²q² + pq is equivalent to p²q³ + pq and pq(pq² + 1)
Answer:
![k = 6](https://tex.z-dn.net/?f=k%20%3D%206)
Step-by-step explanation:
![x {}^{2} + kx + 9 = 0](https://tex.z-dn.net/?f=x%20%7B%7D%5E%7B2%7D%20%20%2B%20kx%20%2B%209%20%3D%200)
here,
a = 1,
b = k
c = 9
now,
![D = b {}^{2} - 4ac](https://tex.z-dn.net/?f=D%20%3D%20b%20%7B%7D%5E%7B2%7D%20%20-%204ac)
![k {}^{2} - 4(1)(9) = 0 \\ k {}^{2} - 36 = 0 \\ k {}^{2} = 36 \\ k = 6](https://tex.z-dn.net/?f=%20k%20%7B%7D%5E%7B2%7D%20%20-%204%281%29%289%29%20%3D%200%20%5C%5C%20%20%20k%20%7B%7D%5E%7B2%7D%20%20-%2036%20%3D%200%20%5C%5C%20k%20%7B%7D%5E%7B2%7D%20%20%3D%2036%20%5C%5C%20k%20%3D%206)
