6x5(x2 - 6x + 3)
When factored it is: (6x-1)(6x+1)
3x2 + 36x + 81 = 3(x2 + 13x + 27)
4x2-36x+81 (2x-9)(2x-9)
4x + 32x + 9 = 36x + 9
6x5(x2 - 6x + 3)
When factored it is: (6x-1)(6x+1)
I take this to be 3x3 - 21x2 + 36x. I notice that 3x is a factor common to all three terms. Let me remove that first. 3x ( x2 - 7x + 12 ) "By inspection" I can make up the two factors in the parenthesised part. 3x ( x - 4 ) ( x - 3 )
3x2 + 36x + 81 = 3(x2 + 13x + 27)
4x2-36x+81 (2x-9)(2x-9)
10x2-36x+18 Divide all terms by 2: 5x2-18x+9 = (5x-3)(x-3) when factored
36x-9y = 15 -9y = -36x+15 y = 4x-5/3 in slope intercept form
52x - 7 = 33 - 36x + 4 52x + 36x = 33 + 7 + 4 88x = 44 x = 1/2
That factors to 4(9x + 5)
4x + 32x + 9 = 36x + 9
81x2 + 72x + 16 = 81x2 + 36x + 36x + 16 = 9x(9x + 4) + 4(9x + 4) = (9x + 4)2
