Answer: A
<u>Step-by-step explanation:</u>
f(x) = x³ + 4x² + 7x + 6
possible rational roots are ±{1, 2, 3, 6}
Try x = -2
-2 | 1 4 7 6
<u>| ↓ -2 -4 -6</u>
1 2 3 0 ← remainder is 0 so x = -2 is a root ⇒ (x + 2) = 0
The factored polynomial x² + 2x + 3 = 0 is not factorable so use the quadratic formula to find the roots.
a=1, b=2, c=3








The factors are:
I think like that but I’m not sure
Answer:
no solution
Step-by-step explanation:
5d - 8 = 1 + 5d
Add 9 to both sides
5d = 9 + 5d
Subtract 5d
0 does not equal 9
No solutions
