Which equation is quadratic in form?

Drupady [299]

we know that

A quadratic equation is a polynomial with an order of two. Its general form is

$ax^{2} + bx + c = 0$

case a) $6(x + 2)^{2} + 8x + 2 + 1 = 0$

$6(x + 2)^{2} + 8x + 2 + 1 = 0 \\ 6(x^{2} +4x+4)+8x+3=0\\ 6x^{2} +24x+24+8x+3=0\\ 6x^{2} +32x+27=0\\\\ a=6\\ b=32\\ c=27$

The case a) is a quadratic equation

case b) $6x^{4} + 7x^{2} - 3 = 0$

The case b) is a grade $4$ polynomial

case c) $5x^{6} + x^{4} + 12 = 0$

The case c) is a grade $6$ polynomial

case d) $x^{9} + x^{3} - 10 = 0$

The case d) is a grade $9$ polynomial

therefore

the answer is

$6(x + 2)^{2} + 8x + 2 + 1 = 0$
