1. x-1= x2
2. 3x2 + y = 15
3. (x + 2)2 = 9+ y
4 - x2-2x + y = 10
5. y - 5 = 4x - 2x​


plsss I need answer now huhuhu

Answer 1

Step-by-step explanation:

Adding 999 to x^2+6xx

2

+6xx, squared, plus, 6, x in row \blueD{(2)}(2)start color #11accd, left parenthesis, 2, right parenthesis, end color #11accd had the fortunate result of making the expression a perfect square that can be factored as (x+3)^2(x+3)

2

left parenthesis, x, plus, 3, right parenthesis, squared. This allowed us to solve the equation by taking the square root.

This was no coincidence, of course. The number 999 was carefully chosen so the resulting expression would be a perfect square.
