P(x) = x + 1x² – 34x + 343
d(x)= x + 9

Step-by-step explanation:

Let us start by isolating x for dx = x + 9.

dx - x = x + 9 - x > dx - x = 9.

Factor out the common term of x > x(d - 1) = 9.

Now divide both sides by d - 1 > . Go ahead and simplify.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
