Add: ab - 4a, 4b - ab, 4a - 4b
Advertisements
उत्तर
(ab - 4a) + (4b - ab) + (4a - 4b)
= ab - 4a + 4b - ab + 4a - 4b
= ab - ab - 4a + 4a + 4b - 4b
= ab (1 - 1) + a (- 4 + 4) + b(4 - 4)
= 0

Add the following:
ab − bc, bc − ca, ca − ab
Simplify combining like terms: (3y2 + 5y - 4) - (8y - y2 - 4)
Add: 14x + 10y - 12xy - 13, 18 - 7x - 10y + 8xy, 4xy
Add: x2 - y2 - 1 , y2 - 1 - x2, 1- x2 - y2
Subtract: - 5y2 from y2
Subtract: (a - b) from (a + b)
What should be added to x2 + xy + y2 to obtain 2x2 + 3xy?
Subtract:
\[\frac{ab}{7} - \frac{35}{3}bc + \frac{6}{5}ac \text { from } \frac{3}{5}bc - \frac{4}{5}ac\]
Multiply: \[\left( \frac{x}{7} + \frac{x^2}{2} \right)by\left( \frac{2}{5} + \frac{9x}{4} \right)\]
Each symbol given below represents an algebraic expression:
= 2x2 + 3y, 
= 5x2 + 3x, 
= 8y2 – 3x2 + 2x + 3y
The symbols are then represented in the expression:
Find the expression which is represented by the above symbols.
