Test your understanding of this lesson Algebraic expression:-

1)
The algebraic expression using variables,constants and arithmetic operations for the statement 'subtraction of y from twice of x' is
  • y-2x
  • 2x-y
  • x-2y
  • 2-xy
2)
'Numbers x andy both squared and added' convert into an algebraic expression and it is
  • x+y
  • 2x+2y
  • x^2+y^2
  • x^2y^2
3)
The coefficient of x in the algebraic expression '\(2x^2y-5xy^2+3y^2\)' is
  • 2y
  • \(3y^2+-5y^2\)
  • 5
  • \(-5y^2\)
4)
Factors of the second term in the algebraic expression '\(5x^3y^2-12ax^2y^3\) are
  • -12
  • -3,2,x,y
  • -2,2,3 x,x,y,y,y,a
  • -12,\(x^2\),\(y^3\)a
5)
'sum of numbers a and b subtracted from their product'is a statement and its corresponding algebraic expression is
  • ab+ab
  • ab-a-b
  • ab-a+b
  • a+b-ab
