Question
Easy
If A = x$^2$ (1 – 3y$^2$), B = x (xy$^2$ – 2x) and C = 3y (y – 4x$^2$y), then A + B – C = px$^2$ + qx$^2$y$^2$ + ry$^2$. What is the value of (5p + q – r) ?

Correct Answer
Option D
Explanation
To solve the problem and verify why Option 4 is the correct answer, we need to evaluate the expression A + B - C and compare it to the form px$^2$ + qx$^2$y$^2$ + ry$^2$. Then, we will calculate the value of (5p + q - r). Given: - A = x$^2$ (1 – 3y$^2$) - B = x (xy$^2$ – 2x) - C = 3y (y – 4x$^2$y) First,…Read More
