80 ! i desperately need ! tell me how to do this! plz(4k+5)(k+1)=0

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

k = - 5/4 or k = - 1

Hope that helps ( k = -5/4 or k = -1)

Use distributive property to get 4k^2 +9k+5 and factor it from there. You should get (4k+5)(4k+4).
