How many intercepts does the graph of y=2x^2+5x+9

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.

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
