Steps to factorise a quadratic expression of the form 𝑎𝑥! + 𝑏𝑥 + 𝑐
1️⃣ Calculate the product of 𝑎 × 𝑐.
2️⃣ Find two factors of 𝑎 × 𝑐 that add up to 𝑏.
3️⃣ Rewrite the expression, substituting 𝑏𝑥 with the two factors found.
4️⃣ Factorise the first two terms and the last two terms of the rewritten expression.
5️⃣ Simplify by taking out the common factor.
