Quadratic Or Not Quadratic If Not Explaintion There Is Wrong Please Can We Answer My Question Please Use Your Mind Please!!!, 1. 3m + 18=5, 2. X2 - X

Quadratic or not quadratic if not explaintion there is wrong please can we answer my question please use your mind please!!!

1. 3m + 18=5
2. x2 - x + 10=0
3. 12 - 4x=y
4. 2t2 - 7t =14
5. 6 - 2x + 3x2 =0
6. 3x (x-5) = -7
7. 1/2 (H-6) = 0
8. (s+2)2 = 0
9. (w-8) (w+9) = w2
10. (x+y) (x+2) =0

 

Step-by-step explanation:

1. 3m + 18=5

Not quadratic because it is a linear equation

2. x² - x + 10 = 0

It is quadratic

3. 12 - 4x = y

It is not because it is a linear equation

4. 2t² - 7t =14

Quadratic

5. 6 - 2x + 3x² =0

Quadratic

6. 3x (x-5) = -7

3x² - 15x + 7 = 0

Quadratic

7. 1/2 (H-6) = 0

Not because it is a linear equation

8. (s+2)2 = 0

s² + 4s + 4 = 0

It is quadratic

9. (w-8) (w+9) = w²

w² + w - 72 = w²

Not Quadratic because it is linear equation

10. (x+y) (x+2) =0

x² + xy + 2x + 2y = 0

Not Quadratic because it is not in the form of ax² + bx + c = 0

Hope it helps:)
