Question

is 2x-1=x2 linear equation in one variable?​

Answer 1

Step-by-step explanation:

» 2x - 1 = x²

» 2x - 1 - x² = 0

For identifying linear equation formula is b² - 4ac, if this equals to a perfect square then it is a linear equation;

In this case we can consider 2x as A and -1 as B and x² as C ....but we will take only the natural numbers nothing else..!

a = 2x , b = - 1 , C = x²

So ; b² - 4ac

= 1² - 4 × 2 × ( - 1)

= 1 - 8 × - 1

= 1 + 8

= 9

So here here 9 is a perfect square it means ...this is a linear

equation...
