Correct method to factor this expression are:
Factor by grouping.
Factor out the GCF.
What is factorization?A number or other mathematical object is factorised or factored in mathematics by expressing it as the product of numerous factors, often smaller or simpler things of the same sort. The four primary methods of factoring are the Grouping technique, the Difference in Two Squares, the Sum or Difference in Cubes, and the Greatest Common Factor (GCF). Numerous issues might be resolved by using the factoring of integers. Similar to this, factoring is an extremely effective method in algebra that is utilised at all levels. It offers a common approach to simplifying complex statements as well as, of course, solving quadratic equations.
The equation becomes:
= 4x² - 26x + 30
= 2 (2x² - 13x + 15)
= 2 (2x² - 10x - 3x + 15)
= 2 {2x (x - 5) - 3 (x - 5)}
= 2 (2x - 3) (x - 5)
Thus, the two methods are the best choices to factor this express are:
Factor by grouping.

Lance is an enthusiastic cyclist.
He uses an app on his phone to track each of his cycling sessions.
Below is shown some information about his last three.
In Lance’s last three cycling sessions.
(i) What was the shortest distance cycled?
(ii) What was the longest time that he cycled for?
(iii) Work out Lance’s cycling time.
Answers
Answer:
17.25 ; 1:01:13 ; 4 hours 47 minutes, 38 seconds
Step-by-step explanation:
From the picture attached :
The shortest distance cycled :
17.25 < 25.80 < 27.42
Hence, shortest distance cycled is : 17.25
Shortest cycling time :
1:01:13 < 1:50:05 < 1:56:20
Hence, shortest distance cycled is : 1:01:13
Total cycling time:
1:01:13 + 1:50:05 + 1:56:20
1 + 1 + 1 = 3 hrs
01 + 50 + 56 = 107 = 107/60 = 1 hr 47 minutes
13 + 05 + 20 = 38 seconds
Total cycling time :
(3 + 1 hr 47 minutes + 38 seconds) = 4 hours 47 minutes, 38 seconds
