Answer:
2(x-1)(x-4)
Step-by-step explanation:
Begin by dividing each term by 2 and pulling the 2 to the front.
This is a trinomial. Trinomials are three term algebraic expressions typically featuring variables to exponent powers. To break these trinomials down we factor them using the diamond method or GCF. The diamond method states that for a trinomial multiply a*c then find two numbers which multiply to this number and add to b. When you find those numbers, write them as
.
a=1, c=4
ac=4 and add to b=-5 which -1 and -4 satisfy
The factored form is 2(x-1)(x-4).
Answer: There are 5 candies of first type and 4 candies of second type.
Step-by-step explanation:
Since we have given that
Number of pieces of candy of first type = 15
Number of pieces of candy of second type = 20
We need to find the greatest number of pieces possible.
So, Greatest number of pieces = H.C.F. of 15 and 20 = 5
So, there are 5 greatest number of pieces possible.
Number of candies of first type in this piece =
Number of candies of second type in this piece =
Hence, there are 5 candies of first type and 4 candies of second type.
