Question

please help me to everyone class 9 math​

Answer 1

To solve this quest first you have to factorise the Expression:

$= > 35y ^{2} + 13y - 12$

Hope you must be knowing middle term splitting

So,

$= > 35y ^{2} + 35y - 12y - 12$

Now take out common factors

$= > 35y \: ( \: y + 1 \: ) - 12( \: y + 1 \: )$

Ans:- ( 35y - 12 )( y+1 )

As the question is asking length and breadth of rectangle SO..,

• Length : ( 35y - 12 )

• Breadth : ( y + 1)
