factor the trinomial 16x^2+24x+9
Since the first and the last term happen to be perfect squares, you can take the square root of each, and check whether the linear term (the central term) happens to be twice the first term, times the last term. In this case it is.
5a(a+2b+b²)
10 + 9x
5
is -11+6= -17?
81x2 + 72x + 16 = 81x2 + 36x + 36x + 16 = 9x(9x + 4) + 4(9x + 4) = (9x + 4)2
http://wolfa.com/input/?i=72x-50y%2B188%3D0 72x-50y+188=0 Rewrite as 72x-50y=-188 x = -188/72 = -2.611 y = -188/-50 = 3.76 For more information and fraction form of the answer, see the link above
72x - 50y + 52z = -188-- At the x-intercept, 'y' and 'z' are zero.72x = -188x = -2.611...-- At the y-intercept, 'x' and 'z' are zero.-50y = -188y = 3.76-- At the z-intercept, 'x' and 'y' are zero.52z = -188z = -3.615 (rounded)
It is a quartic equation in the variable x.
2x + 3 = 72x = 4x = 2
35x^2 + 77x + 42 Improved answer: 5x+67x+7 When simplified = 72x+7
If that's 16x2 + 72x + 81, that factors to (4x + 9)(4x + 9) or (4x + 9)2
8x2 - 10x - 3 = (2x - 3)(4x + 1)
-64
Since the only variable, "x", is not a common factor, you just need to calculate the common factor of the numbers.In this case, you might start with the smallest number, check whether it's a factor of the others. If it is, that's the answer; if it isn't, the greatest common factor will be one of the factors of this smallest number.
