(2x+3)(x+3)
(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
2x + 9
Oh, dude, you're trying to pull a fast one on me, huh? 2 times what divided by 3 equals 6? That would be 12, my friend. So, technically, 2 times 12 divided by 3 does equal 6. Math can be sneaky like that, right?
If 9-2x =35 -2x = 35-9 -2x = 26 -x = 13 x = -13
(2x - 9)(2x - 9) or (2x - 9)2
9(2x - 1)(2x + 1)
If you mean: 2 times (8+7)-6 then divided by 2 times (9-3) then the answer is 2
4x^(2) - 81 First remember the two numbers are both squared numbers. 4 = 2^(2) & 81 = 9^(2) Hence (2x)^(2) - 9^(2) Next remember two squared terms with a negative(-) between them , will factor. Hence (2x - 9)(2x + 9) Note the two different signs. NB Two squared terms with a positive (+) between them does NOT factor. .
4x2 - 9 = (2x + 3)(2x - 3)
(x - 1)(2x - 9)
(2x+3)(x+3)
(2x - 3)(2x - 3)
90
3 squared = 9 9 - 2 x 1 = 9 - 2 = 7
If you mean: 4x squared+12x+9 then it is (2x+3)(2x+3)
(2x+3)(x+3)
