Question

Which statement best describes the equation x + 5 imprint c squared + 4 (x + 5) + 12 equals 0

Answer 1

Given:

`(x+5)^2+4(x+5)+12=0`

let u = x+5

so, the equation will become:

`u^2+4u+12=0`

so, the equation is quadratic in form because the substitution u = x+5

The answer is the first statement

Note:

the second statement is wrong, because when the equation expanded, it will be a second degree polynomials not fourth degree

Also, the last 2 statements are wrong, because it is quadratic equation.
