Answer:
p = - 2, p = - 
Step-by-step explanation:
Given
3p(2p - 1) - 17 = (2p - 5)² ← expand factors on both sides
6p² - 3p - 17 = 4p² - 20p + 25 ( subtract 4p² - 20p + 25 from both sides )
2p² + 17p - 42 = 0
Consider the factors of the product of the coefficient of the p² term and the constant term which sum to give the coefficient of the p- term.
product = 2 × - 42 = - 84 and sum = + 17
Factors are + 21 and - 4
Use these factors to split the p- term
2p² - 4p + 21p - 42 = 0 ( factor the first/second and third/fourth terms )
2p(p - 2) + 21(p - 2) = 0 ← factor out (p - 2) from each term
(p - 2)(2p + 21) = 0
Equate each factor to zero and solve for p
p - 2 = 0 ⇒ p = 2
2p + 21 = 0 ⇒ 2p = - 21 ⇒ p = - 
Answer:
(x-3) (x+5)
Step-by-step explanation:
After determining that there was no GCF, I just used the trial an error method using the factors of 15. For small numbers like the one provided, it is pretty fast and effective.
Answer: 90
Step-by-step explanation: We know that, every 20 shots he attempts, he makes 18. He has a 90% success rate. If he attempts 100 free throws, he would make 90% of them, which is 90!
Another way to solve it is note that 100 is 20*5, so 18*5 is 90, which is also our answer.
