∙ 12y agob^2 - 4ac
Is the discriminant.
6^2 - 4(3)(5)
36 - 60 = - 24 < 0
so, an unreal answer and no real X intercepts

21x3-35x2+14x = 7x(3x2-5x+2)
The discriminant, ( first positive 4 in the constant, then negative 4 as you did not specify this ) b2 - 4ac ------------ (- 7)2 - 4(3)(4) 49 - 48 = 1 ============a positive number means two real roots ( - 4 now ) ( - 7)2 - 4(3)(- 4) 49 + 48 = 97 ============still positive and two real roots
It is of the 2nd degree.
16? using 16, you have (3x2 + 4)(3x2 + 4) = 9x2 + 24x + 16
49-(4*3*4) = 1
The discriminant is -32.

The degree of this polynomial is 2.
It is a second degree polynomial.
x3 - 3x2 + x - 3 = (x2 +1)( x - 3)

3x2 + 33x + 54 =3(x2 + 11x + 18) = 3(x + 9)(x + 2)

Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. The sign for the constant term is missing! Assuming it is meant to be a + the discriminant = (-4)2 - 4*(-3)*(1) = 16 + 12 = 28

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
