First, simplify the (x+2)(x+2) with FOIL:
f(x)=(
)-3
Combine like terms
f(x)=
Then you have standard form.
Hope that helps.
Touch the x axis means the zeroes (y=0) of theh equation aka the roots aka the solutions
ok, so remember that the degree of the polynomial will be the maximum number of roots so therefor
minimum degreee is 5th degree
It is a knowledge check
On aleks
If it was physics or math try to solve all problems you have and try to search for more questions to solve the more you solve the more you will gain marks ,if it was a subject that needs to memorize write down the things you forget on nots and read them in the morning .. do not forget to take a break whenever you lose your passion just believe in yourself you can do it
