Answer:
the forumal to find thr mean is the sum of terms divided by the number of terms.
X^2 - 18x - 144 = 0
Factorise:
We choose 2 numbers that add to -18, and multiply to 144, these numbers are +6 and -24, we put it into the brackets:
<span>(x + 6)(x - 24) <- x = the interted sign of the numbers inside the brackets
E.g. +6 turns into -6 and -24 turns into +24
x must = -6 or = +24
</span>
20-6=14
14+8=22
22*4=88
88+12=100

Answer:
Step-by-step explanation:
m^2-40+6m
=m^2+6m-40
=m^2-(10-4)m-40
=m^2-10m+4m-40
=m(m-10)+4(m-10)
=(m+4)(m-10)
