(k - 1)(k - 4)
Use FOIL to solve this.
First
k * k
Outer
k * -4
Inner
-1 * k
Last
-1 * -4
k^2 - 4k - 1k + 4
k^2 - 5k + 4 is the trinomial.
20( -1.5r + 0.75)
Multiply everything by 20
= -30r + 15
To be honest I’m not sure but I believe it’s -7 if there’s anymore information please attach it along with your question
