2 answers:
Answer: x=-1
Step-by-step explanation: 2 times 2 is 4 plus 7x plus 3. Move 4 and 3 over and you get negative 7. Divide by 7 and x=-1.
Answer:
x = -1/2 and x = -3
Step-by-step explanation:
2x² + 7x + 3 = 0
Using AC method:
2 × 3 = 6
Factors of 6 that add up to 7: 1 and 6
Divide by 2 and reduce: 1/2, 6/2 = 3/1
The factors are (2x + 1) and (x + 3)
(2x + 1) (x + 3) = 0
2x + 1 = 0
x = -1/2
x + 3 = 0
x = -3
The solutions are x = -1/2 and x = -3.
