Question

What is the degree of the equation x2

+ 2x – 3 = x2

+ 7x -- 23

(i) zero

(ii) one
(iii) two

(iv) three​

Answer 1

Answer:

(ii) one

Step-by-step explanation:

The degree of polynomials in one variable is the highest power of the variable in the algebraic expression.

$x^{2} + 2x - 3 = x^{2} + 7x - 23$

will reduce to

2x - 3 = 7x - 23 ( $x^{2}$ gets cancelled on both sides )

=> 7x - 2x - 23 + 3 = 0

=> 5x - 20 = 0

Here the highest power of x is 1 thus option (ii) one
