### Grade 7 - Mathematics4.2 Factorization by Rearrangement of Terms

 Example: Factorize ax-by-ay+bx. Solution: Rearranging  the given terms, we have = ax-ay+bx-by = a(x-y) + b(x-y) = (a+b)(x-y) Therefore ax-by-ay+bx = (a+b)(x-y) Directions: Solve the following problems and show your work. Also write at least ten examples of your own.
 Q 1: Factorize x3 - 2y + 2x2 - xy.(x2+y)(x+2)(x2-y)(x-2)(x2-y)(x+2) Q 2: Factorize cp + 6dq - 2cq - 3dp.(c+3d)(p-2q)(c-3d)(p-2q)(c-3d)(p+2q) Q 3: Factorize 3a + 12 - ab - 4b.(a-4)(3-b)(a+4)(3+b)(a+4)(3-b) Q 4: Factorize a + y + 1 + ay.(1-y)(a+1)(1+y)(a-1)(1+y)(a+1) Q 5: Factorize a - b - a2 + b2.(a-b)[1-(a-b)](a+b)[1-(a-b)](a+b)[1-(a+b)] Q 6: Factorize 3xz + 2y - yz - 6x.(3x-y)(x+2)(3x-y)(x-2)(3x+y)(x-2) Question 7: This question is available to subscribers only!
