Detailed Solution
Download Solution PDFदिलेले आहे:
वर्ग समीकरण y2 + 4y + 4 = 0
संकल्पना:
दिलेल्या कोणत्याही वर्ग समीकरणासाठी,
ax2 + bx + c = 0
मुळे \(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)
संकल्पना:
वर्ग समीकरण y2 + 4y + 4 = 0
\(y = {-b \pm \sqrt{b^2-4ac} \over 2a}\)
a = 1, b = 4, c = 4
\(y = {-4 \pm \sqrt{{(-4)}^2-4(1)(4)} \over 2(1)}\)
\(y = {-4 \over 2}=-2\)
y = -2, -2
म्हणून, पर्याय 1 योग्य आहे.
