You can find the x intercept by setting y to 0 and factor the equation.
0=2x^3+3x-2
0=(2x-1)(x+2)
We can make this equation =0 if x is -2 and 1/2.
So the x intercepts are (-2,0) and (0.5,0)
Step-by-step explanation:
i beleive this is what your looking for sorry if its not.
To divide a fraction by a fraction, multiply the first fraction by the reciprocal of the second one. That means, keep the first fraction the way it is. Change the division to a multiplication. Flip the second fraction.
-8/3 / -2/6 = -8/3 * -6/2 = (8 * 6)/(3 * 2) = 8

Here it is answer do others your self bcz it's easy
Answer:
–x² + 12x + 5
Step-by-step explanation:
x² + 3x
–2x² + 9x + 5
The sum of the above expression can be obtained as follow:
.... x² + 3x
+ –2x² + 9x + 5
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
–x² + 12x + 5
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Thus, the sum of x² + 3x and –2x² + 9x + 5 is –x² + 12x + 5
