x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
(a) y = -3x + 1
Set the equation equal to zero. 3x2 - x = -1 3x2 - x + 1 = 0 The equation is quadratic, but can not be factored. Use the quadratic equation.
The equation is equivalent to: -3x2 - 12x - 1 = 0 [you could change signs to get 3x2 + 12x + 1 = 0 but that is not required] The discriminant is (-12)2 - 4*(-3)(-1) = 144 - 12 = 132
With difficulty because it's not an equation but an expression.
3x2 + 17x + c = 0, rearranging gives c = -3x2 - 17x
y2=x3+3x2
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0

No. Y=3X2+1 is a Binomial Equation.
y2-3x2+6x+6y= 18 is in standard form. The vertex form would be (y+3)2/24 - (x-1)2/8 = 1
It has one double solution.
(a) y = -3x + 1
3x2 + 2x - 8 = 0 is a quadratic equation.
3x2=6+38=44
It is: 3x2-5x-2 = 0 and the value of x is -1/3 or 2 when solved
