Factorize the following: 9{p-q}²-25{q-r}²

Mathematics
1 answer:
anyanavicka [17]2 years ago
6 0

Step-by-step explanation:

Using the identity a² - b² = (a + b) (a - b)

=> (3 {p - q})² - (5 {q - r})²

=> [(3 {p - q}) + (5 {q - r})] [(3 {p - q}) - (5 {q - r})]

=> [(3p - 3q) + (5q - 5r)] [(3p - 3q) - (5q - 5r)]

=> [3p - 3q + 5q - 5r] [3p - 3q - 5q + 5r]

=> [3p + 2q - 5r] [3p - 8q + 5r]

can terms be separated by multiplication signs or are they only separated between plus and minus signs?
Katen [24]

<span>the product of a number and the same number less 3 
x(x – 3)</span>

The words "the product of" tell us we're going to multiply a number times the number less 3. In this case, we'll use parentheses to represent the multiplication. The words "less 3" tell us to subtract three from the unknown number.

a number divided by the same number less five

The words "divided by" tell us we're going to divide a number by the difference of the number and 5. In this case, we'll use a fraction to represent the division. The words "less 5" tell us we need a minus sign because we're going to subtract five.

I WILL GIVE BRAINLIEST! PLEASE HELP ME
Over [174]

1.) c. x^2−2x+4−14/x+2

2.) The remainder is 1/2x-1. When you divide 8x^2+4x−3 by 2x-1, your answer is 4x+4 remainder 1/2x-1.

3.)The remainder is 6/(x+3) because when you divide 7x^2+15x−12 by x+3, you get 7x-6 remainder 6/x+3


The work is attached if you need it, sorry for the messiness!
