Answer:
1-a2
1-5x2
-4x2= -8
Step-by-step explanation:
X - 18 = 35. 53 is x, since 53 - 18 = 35.
if we zero out f(x), namely make y = 0, we can get the roots or x-intercepts for this quadratic equation

now, the equation is in x-terms, meaning is a vertically opening parabola, so the axis of symmetry will be x = something, a vertical line.
well, we have two x-intercepts, one at -4 and another at 2, and the vertex is right half-way between those guys
-4------------(-1)------------2
so the vertex is at x=-1, namely the axis of symmetry is x = -1.
The answer is 30 because i had this on a test
X= -3
Solution:
takeaway 4 from each side
x+3=0
subtract 3 from each side
x=-3
