-9x = 81x²   ≡   81x² + 9x + 0 = 0\nFor cuadratics with the form ax² + bx + c = 0 use this formule:\n\nx = [-b± √(b²- 4ac)] / (2a)\n\nso:\n\nx = [-9 ± √(9² - 4(81)(0))] / (2(81))\nx = [-9 ± √(9²)] / 162\nx = [-9 ± 9] / 162\n\nx = a = 0\nx = b = -18 / 162 = -9 / 81 = -1 / 9\n\nsubstitute and confirm it 0 = 0 for both a and b answers.

You got it right so far. But next...to multiply by 1/4...is the same thing as dividing by 4. So take 4x^2/4=x^2 and then -4/4=-1...so you get x^2-1...make sense? I hope I helped...God bless.

are u sure its not supposed to be the other way around. Cuz that would make a little more sense.\n\nBut if not, then it would probably be:\n1 + ((4s squared - 11) / (s to the 4 - 3s squared -11))\n1 the quotient. the rest the remainder.

If u could give the entire question i could solve it for u and i'm not jokin. its actually quite easy.Its basically\n\n(w+3)/4w * 2w/(w-3).So wat ud have is\n\n1/2( (w+3)/(w-3) )\n\nits xactly like sayin 2/4 = (2/1) / (4/1)

I'm not sure what you mean by ***, so I'll answer the second part of your question.\n\n-4x/-4x + 12/-4x = 1 - 3/x

4, 0, -2, -2, 0\n\nFigure it out! Don't be lazy!

You need to give some directions.  What is the problem asking you to do?\nNote: The person below is incorrect.  (4+3x)^5 does NOT equal\n4^5 + (3x)^5

(1+1)-2*3/2^2+2\n\nWithout useing Order of Operations: 2\n\nWith Order of Operations: 2.5

4x + 6 is not quite right\nwatch the order of operations and distributive properties\n\nrepost your answer and I'll tell you if you got it\n\n(you didn't think I'd just give up the answer, did you ?)

so you have (1/2)a+a-(6/3)=4+(1/3)a\n\nadding like terms: (3/2)a-2=4+(1/3)a\n\nsubtract (1/3)a from (3/2)a and add two to both sides:\n(3/2-1/3)a=4+2\n(9/6-2/6)a=6\n(7/6)a=6\n\nnow solve and what do you get? :)

Subract the two terms on the left giving:\n-2t < 16\n\nAdd 2t to both sides giving\n0 < 16 + 2t\n\nSubtract 16 from both sides\n\n-16 < 2t\n\nDivide both sides by 2\n\n-8 < t

Hello again darling \n\n3(m-2)-(m=4)=8\n\n● Step 1 \n3(m-2) = \n(3 * m) + (3 * -2 ) =\n3m - 6\n\n● Step 2\n-(m - 4)= \n-m + 4 \n\n● Step 3\n3m - 6 - m + 4 = 8\n( 3m - m ) = 8 +6 - 4\n2m = 10\nm = 10 / 2\nm = + 5\n\nGood Luck Sweetheart ♣

I'm sorry, but how could you not know this?\nThis is basic elementary math and if you don't know how to round you are in trouble.\nIt's 0.1 by the way

[ (50000 x 2.4)+(25000 x .8) ] / (50000+250000)=1.8\n\nThe remainder of the info in the problem is not necessary.

Please see the answer above and find out the missing factor in your calculation. You are in the right track. All the best!

C is correct but not complete... only the 3 is factored out... the real answer would be:\n\n3(x-1)(x+4)
