Answer: It’s A
Step-by-step explanation:
to identify all of the Sims, products and factors in the expression you have to work it out step-by-step so basically we have x + 5, y + 9 + 2 + x parentheses y + 23 and then you multiply and start from there
Answer:
y² - (K- 2)y + 2k +1 = 0
equal roots means D=0
D= b^2 - 4ac
a=1, b= (k-2), c= 2k+1
so,
(k-2)^2 - 4(1)(2k+1) = 0
=> k^2 +4 - 8k -4 = 0
=> k^2 -8k = 0
=> k^2 = 8k
=> k= 8k/k
=> k = 8
Therefore the answer is k= 8
Hope it helps........
