Question

Give possible expressions for the length and breadth of the following rectangle, in which its area is given.
Area: 25a² -35a +12

Answer 1

Step-by-step explanation:

25a2 -35a +12= 25a2 -20a -15a + 12

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

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

hence, length= 5a-4 or 5a-3

breadth= 5a-3. or 5a-4

Answer 2

Answer:

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

Step-by-step explanation:

25a²-35a-12

we will first factorise these quadratic equation using splitting the middle term,

then,

25a²-20a-15a+12

taking common from these expressions

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

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

hence we got length and breadth....
