For x intercepts, plug in 0 for y.
0 = (x^2) - 2x - 35
*factoring* = (x-7)(x+5)
x intercepts = 7,-5
As for the vertex, you can use the equation -b/2a for the x-coordinate of the vertex
so,
x = -b/2a = -(-2)/2 = 1
then just find the y value by plugging it back in to the equation.
y = ((1)^2) - 2(1) - 35
= -36
so, vertex is at (1,-36)
Follow these steps and you should get your answer its not the same questions but it should help
The answer to the problem is as follows:
These two polynomials are 5x^2 + 3x + 5 and 3x^2 +2x + 2:
Subtracting the second expression from the first:
<span>5x^2 + 3x + 5
- (3x^2 +2x + 2)
</span>____________
<span>2x2 + x + 3 <------------- The difference

12%
40% = 0.4
30 = 0.3
0.3 x 0.4 = 0.12
0.12 = 12%
