9x2-9x = 0 x2-x = 0 x(x-1) = 0 x = 1 or x = 0
I x=5 and y=2, then (5x5)=25 plus (9x2)=18. 25+18=43
9x-53=6/x 9x2-53x=6 9x2-53x-6=0 9x2+x-54x-6=0 x(9x+1)-6(9x+1)=0 (9x+1)x(x-6)=0 9x+1=0 or x-6=0 9x=-1 or x=6 x=-1/9 or x=6
well you gotta distribute the 3s and the x's so it will be like 3X3 xXx (3 times 3) (x times x)so u should get like... 9x2
Well, darling, if you do the math, 83 divided by 3 is approximately 27.67. So, technically, 27.67 times 3 equals 83. But let's be real, if you're looking for a whole number solution, then 27 times 3 equals 81, not 83. Math can be a real pain in the neck sometimes, can't it?
9x2-9x = 0 x2-x = 0 x(x-1) = 0 x = 1 or x = 0
x = 4
9x2 + 7x = 2 9x2 + 7x - 2 = 0 9x2 + 9x - 2x - 2 = 0 9x(x + 1) - 2(x + 1) = 0 (9x - 2)(x + 1) = 0 x ∈ {-1, 2/9}
9x2+6x-7 = 0 Using the quadratic equation formula:- x = 0.6094757082 or x = -1.276142375
83 x 1
x=5
9x2 + 3x / 3x equals (3x + 1).9x2 + 3x divided by x is 9x + 3 , and then divided by 3 yields the 3x +1.
1 x 83.
3 x 6 = 18
I x=5 and y=2, then (5x5)=25 plus (9x2)=18. 25+18=43
9x2 = 2x Get the 2x to the left side to get 9x2 - 2x = 0 Use cuadratic formula to solve for x knowing that c is 0 x = [ -b +- sqrt (b2-4ac) ]/2a
