Hey i was just wondering if anyone can give me a better explanation on how to work with negative numbers and and fractions when factorisation. it’s just a bit confusing on how to work those kind of equations out. i’ll put a picture of like examples of the questions i have to answer, all i’m asking is just a basic explanation and a step by step equation on how it works

see explanation

Step-by-step explanation:

Given

Distribute the 3 parenthesis on the numerator

=

Collect like terms on the numerator

=

Divide each of the terms on the numerator by 4

= + +

= - 6a + 9b - 12c ← factor out - 3 from each term

= - 3(2a - 3b + 4c)

Compare with

X(2a + Bb + Cc) to obtain

X = - 3, B = - 3, C = 4

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
