Question

1. Three less than the square of a number can be

Answer 1

Answer:

D) $x^2-3$

Step-by-step explanation:

As if a statement is given which says that :Three less than the square of a number.

This means  $x^2-3$ if the number is 'x'

Suppose the statement is : the value of y is 3 less than the square of x then the equation will be $y=x^2-3$

By using two such statement that gives two equation we can find the value of x and y by solving one equation and putting it in the other equation which will give the values of two variables .
