Use the distributive property to factor the expression below. 5x2 + 25

1 answer:

6 0

First you need to find the highest common factor of 5x² and 25, which is 5 because there is no x term in 25. This means that 5 goes on the outside of the brackets, like 5 (______). To get 5x² from 5, you need to multiply by x², which is your first term in the brackets. To get 25 from 5, you need to multiply by 5, which would be your second term, so your final answer is 5(x² + 5). I hope this helps!

28 prime factorization

sineoko [7]

Answer:

2 x 2 x 7, or 2^2 x 7

Step-by-step explanation:

Let us use prime factorization to find the prime numbers that make up 28:

28 = 2 x 14

2 is a prime number, 14 is not, so we have our first prime, 2.

14 = 2 x 7

We then further break the number down into two prime numbers, 2 and 7. Since 2 and 7 are prime and we can't break them down any further our answer is 2 x 2 x 7, or 2^2 x 7.
