81x - 126x ÷ 3x + 1
45x / 3x + 1
15x / x + 1
Lets solve your equation step by step:
(4k + 5)(k + 1) = 0
Step 1: Simplify both sides of the equation:
4k^2 + 9k + 5 = 0
Step 2: Factor left side of equation:
(4k + 5)(k + 1) = 0
Step 3: Set factors equal to 0:
4k + 5 = 0 or k + 1 = 0
k = - 5/4 or k = - 1
Answer: k = - 5/4 or k = - 1
Hope that helps!!!! ( Answer: k = -5/4 or k = -1)
