Answer: 7(x+2)(x+3)

Step-by-step explanation:

First, you want to find the GCF, 7 goes into all the terms evenly

so 7x^2 + 35x + 42 = 7(x^2 + 5 + 6)

to factor (x^2+5+6), you want to find two numbers whose product is 6 and whose sum is 5 (2 and 3)

so (x^2 + 5 + 6) becomes (x+2)(x+3)

and 7(x^2 + 5 + 6) becomes 7(x+2)(x+3)

Find two consecutive numbers whose squares differ by 45
Wittaler [7]

Answer:

The 2 numbers are 22 and 23

Step-by-step explanation:

let the two numbers be x and x+1

according to the question:

(x+1)^2 - x^2 = 45

x^2+1+2x - x^2 = 45

2x + 1 = 45

2x= 44

x = 22

the other number is x+1 = 22+1 = 23

therefore, the two consecutive numbers are 22 and 23
