Question

factorise the following​ with solution​

Answer 1

Answer:

9(3x+2)²-4(2x-1)²

=[3(3x+2)]²-[2(2x-1)]²

=(9x+6+4x-2)(9x+6-4x+2)                     [a²-b²=(a+b)(a-b)]

=(13x+4)(5x+8)

Answer 2

Answer:

ii. 9(3x+2)² - 4(2x-1)²

9(9x²+12x+4)-4(4x²-4x+1)

81x²+108x+36-16x²+16x-4

81x²-16x²+108x+16x+36-4

65x²+124x+32
