Question

what is the value of 25a^2-35a+12

Answer 1

Given Area:

25a²-35a+12

To Find :

Length and Breadth

Solution :

Factorising 25a²-35a+12

[By mid term spilting]

25a²-20a-15a+12

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

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

Length = 5a-4

Breadth = 5a-3

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.
