Quadratic equation is an equation of degree two 
#2 <----- exponent 2

1. x#2-5x+10=0
2. 2t#2-7t=12
3. 2x#2+3x=7
4. y=2x#2+x+1
5. 3x#2-11x+4=0

Thats all :) Tnx :)

*2 = exponent :)

1. 3x-2x*2=7
2. 5-2x*2=6x
3. (x+3(x+4)=0
4. (2x+7)(x-1)=0
5. 2x(x-3)=15

" sf " means standard form

answer :
1. -2x*2+3x-7=0
    sf : a=-2 , b=3, c=-7
2. -2x*2-6x+5=0
    sf : a=-2, b=-6, c=5
3. x*2 +7x+12=0
    sf : a=1, b=7, c=12
4. 2x*2+5x-7=0
    sf : a=2, b=5, c=-7
5. 2x*2-6x-15=0
    sf : a=2, b=-6, c=-15
