Todor was trying to factor 10x^2-5x+1510x2−5x+1510, x, squared, minus, 5, x, plus, 15. He found that the greatest common factor of these terms was 5 and made an area model:

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
