Questions + Answers key
Take MCQ Maths Test1.
Factorise x2 + yz + xy + xz
2.
Factorise :2m3-5m2+9m
3.
Sethu travelled (4x2+3xy2+5x)km in ‘2x’ hrs. Find his speed of travel.
4.
Divide : (5y3 − 25y2 + 8y) by 5y
5.
Velu pastes ‘ 4xy ’ pictures in one page of his scrap book. How many pages will he need to paste 100x2y3pictures? (x, y are positive integers).
1.
We have, x2 + yz + xy + xz
Group the terms suitably as = (x2 + xy) + (yz + xz)
= x(x + y) + z(y + x) (addition is commutative)
= x(x + y) + z(x + y) [taking out the common factor(x + y)]
2.
We have,2m3-5m2+9m taking out the common factor ‘m’ from each term, we get
= 3(2m2-5m+9)
3.
\(speed=\cfrac { distancetravelled }{ timetaken } \)
= \(\cfrac { { 4x }^{ 2 }+3{ xy }^{ 2 }+5x }{ 2x } \)
= \({ 2x }^{ 2-1 }+\cfrac { 3 }{ 2 } { y }^{ 2 }+\cfrac { 5 }{ 2 } \)
Speed = \(\left( 2x+\cfrac { 3 }{ 2 } { y }^{ 2 }+\cfrac { 5 }{ 2 } \right) \) km/hr
4.
We have, (5y3 − 25y2 + 8y) ÷ 5y
= \(\cfrac { { 5y }^{ 3 }-25{ y }^{ 2 }+8y }{ 5y } \)
= \({ y }^{ 3-1 }-{ 5y }^{ 2-1 }+\cfrac { 8 }{ 5 } \)
= \({ y }^{ 2 }-5y+\cfrac { 8 }{ 5 } \)
5.
Total number of pictures = 100x2y3
Each page contains = 4xy pictures
= 25xy2 pages
