maths past papers

I came across a few commonly asked questions in maths past papers which i have mentioned below. We been discussing on various math questions till date and solved them also.

Look below for the simple examples which are asked in previous papers.

Example 1:

Multiply: ( x + 9) ( x + 5 )

Solution:

( x + 9 ) ( x + 5 ) = x ( x + 5 ) + 9 ( x + 5 )

= x2 + 5x + 9x + 45

= x2 + 14x + 45


Example 2:

Calculate the perimeter of rectangle with the length and width are 12 cm and 14 cm.

Solution:

Perimeter = 2( l+ w )

= 2( 12 + 14 )

= 2 (26)

= 52 cm


Now start looking for more questions once you finish it start checking math answers..and if you have any topic that i can discuss with you..keep me informed.
