Given Question :
What should be subtracted from 3x² + 2x - 5 to get - 2x² - 3x + 1 ?
Solution :
To find what should be subtracted from 3x² + 2x - 5 to get - 2x² - 3x + 1 let us add these terms .
So now we have ,
= 3x² + 2x - 5
+ (-2x²) - 3x + 1
____________
x² - x - 4
____________
So therefore x² - x - 4 should be subtracted from 3x² + 2x - 5 to get - 2x² - 3x + 1
More to know :
What are like terms and unlike terms ? What is coefficient , variable and constant ? .Constants are numbers that have a fixed value . Variables are the terms whose value is unknown . Their value is not fixed while solving linear equations often will at their value as alphabets . Generally they are x , y and z . When two numbers have same variables we call them as like terms for example , 2x and 8x both the constants have x as a variable in common . Similarly two numbers with different variables are called unlike terms like 43xy , 87y² .
