Question

factories 25a^2-35a+12​

Answer 1

Answer:

( 5a - 4) ( 5a - 3 )

Step-by-step explanation:

25a² - 35a + 12

sum = -35 = -20 + -15

product = 300 = -20 × -15

25a²- 20a - 15a + 12

5a ( 5a - 4 ) - 3 ( 5a -4 )

(5a - 4) ( 5a - 3 )

Hope this will help you.

Answer 2

hi mate,

solution:

Factoring 25a²-35a+12

25a² - 20a - 15a - 12

Step-1 : Add up the first 2 terms, pulling out like factors :

5a • (5a-4)

Add up the last 2 terms, pulling out common factors :

3 • (5a-4)

Step-2 : Add up the four terms of step 1 :

(5a-3) • (5a-4)

Which is the desired factorization

Final result :

(5a - 4) • (5a - 3)

length = (5a - 4) and breadth = (5a - 3)

or a = 4/5 and a = 3/5

i hope it helps you.
