How do you factor 18x plus 12x2 plus 2x3?
That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: (8 plus or minus the square root of 10) divided by 3 x = 3.720759220056127 x = 1.6125741132772067
Show whether 0 3 is the solution of the linear system below 2x plus y equals -3 x plus 2y equals 8?
For (x, y) = (0, 3) the first equation gives: 2*0 + 3 = -3 that is, +3 = -3 which is FALSE. So (0, 3) is not a solution.
2x3 plus 4x2 plus 8x factor the polynomial?
Take out the common factor, 3: 3x + 6 = 3(x + 2).
How do you factor -x square plus 10x-25 equals 0?
4x2-4x-3=0 can be written as (2x-3)(2x+1)=0 Anything times by 0 equals 0 ( the zero property of multiplication) therefore we need to make each one of these terms in brackets equal to 0. so 2x-3=0 giving x=3/2 and 2x+1=0 giving x=-1/2
Factor this 9x2 plus 27?
9x(x2+3x-10) * * * * * 9x3 + 27x2 - 90x = 9x(x2 + 3x - 10) = 9x(x + 5)(x - 2).
Solve 2x plus 3 equals 9 x equals?
2x+3=9x 3=9x-2x 3=7x x=3/7
How do you slove 2x plus 3 equals 9x?
2x+3=9x-2x -2x3=7x/7 /73/7=x
How do you solve 2x plus 3 equals 9X equals?
2x + 3 = 9x Subtract 2x from both sides: 3 = 7x Divide both sides by 7: 3/7 = x
What is the answer to 9x plus 3-2x equals -11?
X= -2
What is 9x plus 5 equals 7x plus 11?
2x+5=11 2x=6 x=3
What is the result of 2x plus 3 equals 9X equals?
2x + 3 = 9x start by bringing the 2x over- minus it from both sides 3 = 7x divide 7 by on sides x= 3/7 x = .4285714285714 repeating.
What is de result of 2x plus 3 equals 9X equals?
2x + 3 = 9x start by bringing the 2x over- minus it from both sides 3 = 7x divide 7 by on sides x= 3/7 x = .4285714285714 repeating. :)
How do you solve 2x-y equals -6 and 2x plus 3y equals 9?
2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9
What is 2x plus 6 plus 9x equals 39?
2x + 6 + 9x = 39 11x + 6 = 39 11x = 39 - 6 11x = 33 x = 3
2x plus 3 equals 9 x equals?
2x+3=9 2x=9-3 2x=6 2x/2=6/2 X=3
6x2 plus 9x equals 0?
6x2 + 9x = 0 3x(2x + 3) = 0 3x = 0 or 2x + 3 = 0 x = 0 or x = -3/2
2x plus 7x minus 10 equals 4x plus 3 minus 2x?
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
