how can i make 2x2 pic
2x2 + 4 + 1 = 2x2 + 5 So, the vertex is (0, 5)
2x2+6x-8 = 72 2x2+6x-8-72 = 0 2x2+6x-80 = 0 (2x-10)(x+8) = 0
I think you mean 6x2-15x-21 2x2-5x-7 2x2-7x+2x-7 x(2x-7)+1(2x-7) (x+1)(2x-7)
It is: 2x^2 -x -21
2 x 2 = 47 x 3 = 21
2x2 - 16x32 2x2=4-16= -12x32= -384

y
2x2 - x = 21Subtract 21 from each side . . 2x2 - x - 21 = 0Factor the left side . . . . . . . . (2x - 7) ( x + 3) = 0If (2x - 7 = 0), then . . . . . x = 3.5If (x + 3 = 0), then . . . . . x = - 3

(2x2 - 1)(2x2 - 1) or (2x2 - 1)2
The outcome is zero.
tn = 2x2 + 3 where x = 1, 2, 3, ...
2x2 + 21x + 49 = (2x + 7)(x + 7)
