Activity 1 Classify each equation as Quadratic or Non-quadratic. For those equations you choose as Non-Quadratic, give your explanation. (2-points each) -3x² - 2x=5 2x - X = -10 2x-5 = x Bx - 2 = x X(X- 1) = -1 42x² = x + 3 (x - 2) (x + 4) = 7 (x) ² - 2x² = 4 100x4 = 25 (x - x + 1 = 0 QUADRATIC NON-QUADRATIC EXPLANATION



​

Answer 1

Explanation:

quadratic equation shoulb be in the form of

ax²+bx+c =0

-3x² - 2x=5 is not in tge form of quadratic equation so it is non quadratic equation

2x-x²=-10 ==> -x²+2x+10 is in the form of

quadratic equation

2x-5=x is a non quadratic equation

8x-2 =x is a non quadratic equation

x(x-1) = -1 ==> x²-x+1 =0 is a quadratic equation

root2x^-2=x+3 ==> x³+3x² - root2 is a non quadratic equation

(x³)²-x+1 = 0 is a non quadratic equation

-2x²+x+4 is a quadratic equation (here root and square will get canceled)

100x⁴ = 25 ==>10x² =5 ==>x²=1/2 ==x²-1/2

is a quadratic equation
