Put the terms in order of decreasing degree, all on the left. When convenient, it is nice to have mutually prime integer coefficients with the leading one positive.
a) x² -2x +1 = 0
b) x² +15 = 0
c) 4x² -12 = 0
or, better, divide out the common factor of 4.
x² -3 = 0
d) 3x² -x -5 = 0

Shown is the standard form for a single-variable second-degree equation. Form varies depending on the nature of the equation. Equations of conic sections have different standard forms, depending on the curve.
N = ((n-1) + 4) + 4, to my understanding.
although your answers seem right written in the columns, but your method of applying numbers to equation seems incorrect in 'expand' column. for example, answer for 3 should be something like this...
3 21 17+4
4 25 21+4
hope it helps.
<span>g(f(x)) = g(-5x+4) = 4(-5x+4) + 5 = 21-20x</span>
Answer:
60%
Step-by-step explanation:
To know the discount, we must know how much that $ 18 represents of the original price, as follows:
18/45 = 0.4
That is, $ 18 is 40% of $ 45
Therefore, to calculate the discount we must subtract what represents 45%, that is, 100%
100% - 40% = 60%
In other words, the discount is 60%
