Answer :
Answer:
1
Step-by-step explanation:
Given a quadratic equation in standard form : ax² + bx + c = 0 (a ≠ 0)
Then the discriminant is calculated as
Δ = b² - 4ac
Given
4x² + 7x + 1 = - 2 ( add 2 to both sides )
4x² + 7x + 3 = 0 ← in standard form
with a = 4, b = 7 and c = 3, thus
b² - 4ac
= 7² - (4 × 4 × 3) = 49 - 48 = 1
