Question

For the algebraic expression 1 - 2x^2 + 6y^2 - 4xy, answer the following questions. (i) What is the coefficient of x. (ii) Find the sum of the coefficients of the literals x^2 and y^2.

Answer 1

Answer:

Answer: Adding the given expressions, we have (i) x3- 2x2y + 3xy2- y3+ ... Now, required expression = (x2 + 2xy + y2) + (3x2 - 4y2 + 9) ... x2 - xy + y2 - x + y + 3 - M = - x2 + 3y2 - 4xy + 1

Answer 2

Answer:

All questions and answers from the Rd Sharma 2018 Book of Class 7 Math Chapter 7 are ... (ii) 2x2y + (- 4x2y) + 6x2y + (- 5x2y) ... Now, required expression = (2x2 - 3x + 1) + (3x2 + x + 7)
