x2 - 4x + 4 factors to (x - 2)(x - 2) or (x - 2)2
X2 + 44x + 43
18 - 44x
8-9x = 143-44x 44x-9x = 143-8 35x = 135 x = 135/35 = 22/7 or 3.'857142' recurring decimals
4x^2 = 16x 16x - 60x = -44x -44x + 225
63x^2 + 44x - 32 = 0 (9x - 4)(7x + 8) = 0
35x2-44x-7 = (7x+1)(5x-7) when factored
Improved answer:5x2+14x+5 = 5-5x2+14x+5 = 0Solve by completing the square:(x+7)2+5 = 0(x+7)2+5-49 = 0(x+7)2 = 44x+7 = + or - the square root of 44x = -7 + or - the square root of 44
11(4x - 2y - 11z)
11(4x - 2y - 11z)
So, 45x2=90Now the problem would be: 90-44x-12The next step is 44x-12= -528Now the problem would be: 90--528The answer would be:618Am I right or am I right?HeHeHe
