quadratic equations​

Answer 1

Step-by-step explanation:

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

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

x^2+2x-2x+1+7=0

x^2+7=0

A polynomial equation of degree 2 is a quadratic equation.

Answer 2

Step-by-step explanation:

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

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

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

x^2 +7 = 0

x^2 = -7

x = square root -7
