Identify Which Of The Following Equation Are Quadratic And Which Are Not., ,

Identify which of the following equation are quadratic and which are not.

3m + 8 = 15
{x}^{2} - 5x + 10 = 0
12 - 4x = 0
2 {t}^{2} - 7t = 12
6 - 2x + 3 {x}^{2} = 0
25 - {r}^{2} = 4r
3x( x - 2) = - 7
\frac{1}{2} (h - 6) = 0
(x + 2 {)}^{2} = 0
(w - 8)(w + 5) = 14

 

Answer:

Step-by-step explanation:

Not

3m+8=15

12-4x=0

1/2(h-6)=0

Quadratic

x²-5x+10=0

2t²-7t=12

6-2x+3x²

25-r²=4r

3x(x-2)=-7

(x+2)²=0

(w-8)(w+5)=14
