Question

factorise x²+xy+8x+8y​

Answer 1

Step-by-step explanation:

X2+xy+8x+8y

=x(x+y)+8(8+y)

=(x+8)(x+y)

Answer 2

Answer:

(x+y) (x+8)

Step-by-step explanation:

• ${x}^{2} + xy + 8x + 8y$
• $x(x + y) + 8(x + y)$
• $(x + y)(x + 8)$

Explanation:

Factorising Polynomials

• If x-2 is multiplied by 4, the answer is 4x-8.
• Thus, 4 and (x-2) are the factors of 4x-8
• Since both 4x and -8 can be divided by 4 , therefore 4 is the common factor of 4x-8
• Type 1: When factorising, some common factors are always taken out first.
• Type 2: Factors found by grouping terms
