They are the zeros have no meaning
Percent formula : is/of = %/100
is = 12
of = 60
% = x
now we sub
12/60 = x/100
cross multiply
(60)(x) = (12)(100)
60x = 1200
x = 1200/60
x = 20
check..
0.20(60) = 12
12 = 12 (correct)
so 20% of 60 is 12
Answer:
Ok so first you want to distribute the -1 in front of the 3x^2-7x+1
Which turns the problem into
X^2+5x-6 -3x^2+7x-1
Then just combine like terms
-2x^2+12x-7
Also ^ followed by the number is the exponent
