Answer:
B and E
Step-by-step explanation:
To verify which are solutions, substitute the given values into the left side of the equation and if equal to the right side then they are solutions.
A
2(20)² + 18(20) = 800 + 360 = 1160 ≠ 20 ← not a solution
B
2(1)² + 18(1) = 2 + 18 = 20 ← solution
C
2(- 2)² + 18(- 2) = 2(4) - 36 = 8 - 36 = - 28 ≠ 20 ← not a solution
D
Is a repeat of C
E
2(- 10)² + 18(- 10) = 2(100) - 180 = 200 - 180 = 20 ← solution
F
2(- 1)² + 18(- 1) = 2(1) - 18 = 2 - 18 = - 16 ≈ 20 ← not a solution
Then B and E are solutions to the equation
