Answer:
-3
Step-by-step explanation:
p(x) = x^2-6x+5
Let x= 4
p(4) = 4^2-6(4)+5
Exponents first
= 16 -6(4) +5
Multiply
= 16 -24 +5
Add and subtract
= -8+5
= -3

May this help you!!!!!!!!!!!
1. a²-5a-6
look for the factors of the last number without a variable so that it's sum is the coefficient of the number which has the variable power 1
a²+a-6a-6
then factor by grouping.
a(a+1)-6(a+1)
(a-6)(a+1)
so do that to others too try it yourself. if you still need help let me know!!!
