Answer 1

Answer:

1(i) (x+1)^2= 2(x-3)

x^2+2x+1= 2x-6

x^2+7=10

It is form ax^2+bx+c

Hence, it is quadratic equation

Answer 2

Step-by-step explanation:

Step-by-step explanation:2x-7x+3=0

Step-by-step explanation:2x-7x+3=0x²-7/2x=-3/2

Step-by-step explanation:2x-7x+3=0x²-7/2x=-3/2x²-2*X*7/4=-3/2

Step-by-step explanation:2x-7x+3=0x²-7/2x=-3/2x²-2*X*7/4=-3/2(X)²-2*X*7/4+(7/4)²-3/2

Step-by-step explanation:2x-7x+3=0x²-7/2x=-3/2x²-2*X*7/4=-3/2(X)²-2*X*7/4+(7/4)²-3/2(x-7/4)²=49/16-3/2

(x-7/4)²-5/4

X=7/4+5/4

X=7/4+5/4

X=12/4
