Question

if 5x^2 - 9xy -4y^2 =0 ,x!=y ,then what is (2x - 3y) : (3x -2y) equal to...
1) 22 :9
2)22:7
3) 23 :23
4) 23 : 3 ​

Answer 1

Answer:

Add and subtract the coefficients of like terms. For example:

$(x^2 + 2x + 1) + (x^2 - 4x + 4) = (2x^2 - 2x + 5)$

Step-by-step explanation:

A polynomial is an expression which contains variables and simple operations (addition, subtraction, multiplication, and exponents). 3x + 5 is a polynomial, for example. Adding and subtracting polynomials means to take two or more of these expressions and combine them into a new one. We'll add another expression to the first example. (3x + 5) + (2x + 3) = 5x + 8.
