Question

Factorise y^2 – 3 y + 2 by using factor theorem

Answer 1

If a consistent system has exactly one solution, it is independent . If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line. ... The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.

Answer 2

Question:

$y^{2} - 3y + 2$

$y^{2} - ( 2 + 1)y + 2$

$y^{2} -2y - 1y + 2$

$y(y - 2) - 1(y - 2)$

$(y - 2)(y - 1)$
