Plz solve step by step using completing square method of quadratic
x2-2x=3

x =  -1, 3.

Step-by-step explanation:

x2 - 2x = 3

Completing the square:

We use the identity: a^2 - bx = (a - b/2)^2 - (b/2)^2:

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

(x - 1)^2 = 3 + 1

(x - 1)^2 = 4

Taking square roots of both sides

x - 1 = +/- 2

x = 2 + 1 , -2 + 1

x =  -1, 3.

europa2433

y > 1/3x

y < = -x + 4

hope this : )
