Question

choose the quadratic equation among these (a)x (x+1)=0 (b) 2x+7=y (c) x2-x(x+4)=0 (d)2(x-3)=0​

Answer 1

Answer:

b) = 2x+7=y

Step-by-step explanation:

because quadratic equation is any equation that can be rearranged in standard form as ax^{2}+bx+c=0 where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no ax^2 term. Wikipedia
