Ex 12.1, 2 (Method 1) Factorise the following expressions. (x) aπ₯^2y + bxπ¦^2 + cxyz aπ₯^2y = a Γ π₯^2 Γ y = a Γ π₯ Γ π₯ Γ y bπ₯π¦^2 = b Γ π₯ Γ π¦^2 = b Γ π₯ Γ y Γ y cπ₯π¦π§ = c Γ π₯ Γ y Γ z So, x and y are the common factors. aπ₯^2y + bγπ₯π¦γ^2 + cπ₯π¦π§ = (a Γ π₯ Γ π₯ Γ y) + (b Γ π₯ Γ y Γ y) + (c Γ π₯ Γ y Γ z) = x Γ y ((a Γ π₯ ) + (b Γ π₯ ) + (c Γ z) = xy (aπ + by + cz)
