Question

Simplify the equation (2x-1)²-4x²+5=0 and show it is not a quadratic equation​

Answer 1

Answer:

x = 3/2

Step-by-step explanation:

(2x-1)²-4x²+5=0

=> 4x²+1-4x- 4x²+5 =0..... ( 4x² gets cancelled )

=> -4x+6 =0..... ( It is a linear equation )

=> -4x = -6

=> x = 6/4.... { Negative (-ve) sign gets cancelled }

=> x = 3/2

Answer 2

Answer:

here is your answer dear ..

Step-by-step explanation:

0 = (2x-1)²-4x²+5

0 = (2x)² - 2x + 1 - 4x² + 5

0 = 4x² - 2x + 1 - 4x² +5

0 = -2x + 6

0 = 2x - 6                          (taking minus common)

0 = x - 3                             (taking 2 common)

which gives us a linear equation.

when a equation is in the form of ax² + bx + c where a =/= 0 the equation is quadratic but this is not satisfied in the above case hence it is not a quadratic equation and is a linear equation

hope this helps you dear..
