12x2 + 20x - 25 IS a polynomial that factors into (2x + 5)(6x - 5)
A trinomial.
20x + 23
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
5x2 + 20x = 5x (x + 4)
12x2 + 20x - 25 IS a polynomial that factors into (2x + 5)(6x - 5)
The discriminant is 0.
5x(3x+4)
(2x + 5)(6x - 5)
It is the same as: 9+20x+20 = 20x+29
4x2+20x+25 (2x+5)^2
The GCF of 20 and 4 is 4. That factors to 4(5x - 1)
A trinomial.
Combine all lie term: x + x - 22x = -20x 2 + 1 = 3 So the answer is -20x +3 or 3 - 20x
If: y = x2+20x+100 and x2-20x+100 Then: x2+20x+100 = x2-20x+100 So: 40x = 0 => x = 0 When x = 0 then y = 100 Therefore point of intersection: (0, 100)
20x + 23
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
