How are 55:100 and 66:120 equivalent?
AlekseyPX

They are both equal to 11/20. 55/100 can both be divided by 5. 55/5 is 11 100/5 is 20 so 11/20. 66/6 is 11 and 120/6 is 20, so 11/20.

I have this equation that I tried to factor:
AleksAgata [21]

The first coefficient is 2 and the last term is 6. They multiply to 2*6 = 12.

Now we must find two factors of 12 that add to 7 (the middle coefficient).

Through trial and error, you should find that:

3*4 = 12

3+4 = 7

So 3 and 4 are the numbers we're after. We'll split the 7m into 3m+4m and use the factor by grouping method as shown in the steps below.

2m^2 + 7m + 6

2m^2 + 3m + 4m + 6

(2m^2 + 3m) + (4m + 6)

m(2m + 3) + 2(2m + 3)

(m + 2)(2m + 3)

(2m + 3)(m + 2)

The order of the factors doesn't matter since something like 2*3 is the same as 3*2.

------------------------------------------------

Verifying the answer:

You can use technology like you did to check the answer, but here's one way to do it without a calculator.

(2m + 3)(m + 2)

n(m + 2) ...... let n = 2m+3

mn + 2n .... distribute

m( n ) + 2( n )

m(2m+3) + 2(2m+3) .... plug in n = 2m+3

m*2m + m*3 + 2*2m + 2*3 .... distribute

2m^2 + 3m + 4m + 6

2m^2 + 7m + 6

We arrive back at the original trinomial, so we have confirmed the answer.

What adds to 1 and multiples to -90
wariber [46]

Answer:

+10 and - 9

Step-by-step explanation:

If we consider the multiples of - 90

± 1, ± 2, ± 3, ± 5, ± 6, ± 9, ± 10, ± 15, ± 30, ± 90

The combination of multiples which multiply to - 90 and add to + 1 are

+ 10 and - 9

since 10 × - 9 = - 90 and 10 - 9 = 1
