hey can anyone do these for me?
Do not expect anyone to do your work. We can help you learn.
sorry can anyone help me?
@e.cociuba Based on the graph of y = x2 − 2x − 3, what is the x coordinate of the positive x-intercept
is the answer 3?
\[y=x^2 -2x -3\] you can use decomposition method, or easier find a value that _x_=3 _+_=-2
foil out the quadratic function and solve for the each X by making each side zero
example \[x^2-2x-24 \] \[(x-6)(x+4)\] -6x4= -24 -6+4= -2
thank you so much
i got 3 when i solved @BukLoon
