How many x-intercepts does the graph of y = 2x^2 + 5x +9 have?
Pepsi [2]

Answer:

2

Step-by-step explanation:

y = 0 at the point where the function intersects x-axis. Thus, yiou have to put

                                              2x2 + x - 10 = 0

and solve the equation. It is better to factor the quadratic expression, which gives us

                                             2x2 + x - 10 = (2x+5)(x-2) = 0

We have 2x +5 = 0     and x-2 = 0. Thus, the intercepts are x = -5/2 = - 2.5    and x = 2.

X2 + 8x + 6
Svetradugi [14.3K]
You could put the ‘+6’ at the start of the equation so it would read as +6(x2+8x) and then expand the bracket as you normally would so you would get x2x6 which would get you 12x and then 6x8x which would get you 48x and then you could group both numbers together as they’re like terms and your final answer would be 60x
