Answer: 9
Step-by-step explanation:
Answer:
2.25
Step-by-step explanation:
Without replacement 26*25*24*23*22
with replacement 26^5
x²-4x-5=0
The given equation is quadratic
So we can perform prime factorisation of it.
factors of -5, that add up to give -4 are -5 and 1
therefore replacing -4x by -5x+x
x²-5x+x-5=0
performing factoring by grouping,
(x²-5x)+(x-5)=0
x(x-5)+(x-5)=0
(x+1)(x-5)=0
x+1=0 and x-5=0
Answer is x=-1 and x=5
Answer:
D. -5
Step-by-step explanation:
