Answer:
In particular, for an expression to be a polynomial term, it must contain no square roots of variables, no fractional or negative powers on the variables, and no variables in the denominators of any fractions.
Step-by-step explanation:
47 square units is the answer on edge

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:
<=> 5x = 3y - 8
3y + 10 = 0 or y - 6 = 0
<=> 5x = 3y - 8
y = -10/3 or y = 6
+) with y = -10/3 => 5x = -10 - 8 <=> 5x = -18 <=> x = -3.6
+) with y = 6 => 5x = 3.6 - 10 = 8 <=> x = 8/5 = 1.6
