Answer:
k = -1, -2.
Step-by-step explanation:
4k^2+12k+8 = 0
Divide by 4:
4(k^2 + 3x + 2) = 0
4(k + 1)(k + 2) = 0
k = -1, -2.
The correct answer would be 25
Answer:
(x-6)*(x+1)=0
Step-by-step explanation:
1) move the 5x to the left side. x^2-5x-6=0
2) find two numbers that add up to -5 AND multiply to -6. (x-6)*(x+1)=0 (-6×1 = -6 ;-6+1=-5)
