The ones that match are
1 and 5
2 and 6
7 and 3
8 and 4
Answer:
5
Step-by-step explanation:
20 divided by 4 = 5
1 x 5 = 5
2x^2 + 4x + 1 = 0
2x^2 + 4x + 1 - 1 = 0 - 1
2x^2 + 4x = -1
X(2x + 4) = -1
X = -1.
2x + 4 = -1
2x + 4 - 4 = -1 - 4
2x = -5
2x/2 = -5/2
X = -5/2.
I believe these are the solutions. If not you can use the quadratic formula to solve for the roots, solutions.
