Svp svp aider moi j ai une equation ​

x^2 + 2.x.3 +3^2 = (2x+3) (x+3)

x^2 + 6x + 9 = (2x+3) (x+3)

x^2 +3x + 3x + 9 = (2x+3) (x+3)

x(x+3) +3(x + 3) = (2x +3 ) (x+3)

(x+3) (x+3) = (2x +3) (x +3)

x+3 = 2x +3

x = 1 ,

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
