Answer 1

Answer:

yes,it is a quadratic equation.

Step-by-step explanation:

16x^2-3=(2x+5)(5x-3)

16x^2-3=10x^2-6x+10x-15

16x^2-3=10x^2+4x-15

16x^2-10x^2+4x-3+15=0

6x^2+4x+12=0

Answer 2

Step-by-step explanation:

16x^2-3=(2x+5) (5x-3)

=>16x^2-3=2x(5x-3)+5(5x-3)

=>16x^2-3=10x^2-6x+25x-15

=>16x^2-10x^2=19x-15+3

=>6x^2-19x+12=0

We see that the above eq.n is in the form of ax^2+bx+c=0 so we can say that 16x^2-3=(2x+5) (5x-3) is a quadratic equation.
