Question

check whether the following are quadratic equation or not x(x²-6) =2(4x+6)​

Answer 1

Answer:

No it isn't

Step-by-step explanation:

since x(x²-6)=2(4x+6)will make x³-6x = 8x+ 12

further x³-14x -12 = 0

And not forming ax²+bx+c = 0 , because it is x² and not x³

a= 1 , b= -14, c = -12
