It is: x2-10x+21 = 0 and the value of x is 3 or 7 when solved
x = -3.27 or -6.73
0
The discriminant is 900.
To solve this, you would normally set up a systems of equations 10x + 2y = 10 10x + 2y = 11 However, it clearly makes no sense and has no answer. To prove this mathematically, subtact the two equations. 10x - 10x = 0 2y - 2y = 0 10-11 = -1 Therefore, it is basically saying that 0 + 0 = -1 Obviously, that is incorrect, so this question has no solutions.
7x2-10x+3=0 (7x-3)(x-1)=0
3x + 10x - 48 = 0 13x = 48 x = 3.692307692

Calculate 10^2 - 4*(-16)*(-20)
x = -3.27 or -6.73
0
x2 + 10x = 0 x2 + 10x + 25 = 25 (x + 5)2 = 25 x + 5 = +-5 x1 = 0 x2 =10
x2 + 9 = 10x x2 - 10x + 9 = 0. (x - 9)(x - 1) = 0. Therefore, x = 1 or 9.
x2 - 10x + 25 = 0(x - 5)(x - 5) = 0x - 5 = 0x = 5
