The value of x in the equation 49x2 plus 56x plus 16 is -2.04.
.56x=9-.44x x=9
7X^2 -56X + 112 = 0 divide through by 7 X^2 - 8X + 16 = 0 factor (X-4)(X-4) X = 4
2(x-32)(x+60)
I'm pretty sure it's x sqaured plus seven
It is: 2x2-7x+6 = (2x-3)(x-2) when factored
How do you solve 4y plus x equals 8
8
-4x2 - 32x + x + 8 = 8x2 - 56x : simplify and group the various terms-32x + 56x + x + 8 = 8x2 + 4x225x + 8 = 12x2 : Now present this as a standard quadratic equation.12x2 - 25x - 8 = 0 : Solving for the roots of a quadratic equation gives :-x = [25 ± √(252 + 4x12x8)] ÷ 2x12 = [25 ± √1009] ÷ 24 = [25 ± 31.765] ÷ 24x = 56.765/24 = 2.365 and x = -6.765/24 = -0.282x = 2.365 and -0.282
If you mean: d = 56x+72y So if: 8 = 56x+72y Then: x = 1/14 and y = 1/18 Check: (56*1/14)+(72*1/18) = 8
2 x 2 = 4
10x - 25 = 4x + 510x - 4x = 25 + 56x = 30x = 5
