यदि कोई द्विघात समीकरण ax2 + bx + c = 0 है
तब,
मूलों का योग (α + β) = −b/a और,
मूलों का गुणनफल (αβ) = c/a
यदि द्विघात समीकरण जिसके दो मूल होंगे, तो दो संख्याओं α और β का हरात्मक माध्य (HM) निम्न द्वारा दिया जाता है,
HM =
अनुप्रयोग:
हमारे पास द्विघात समीकरण निम्न है,
(5 +
अतः,
a = (5 +
b = - (4 +
c = (8 +
उपरोक्त सूत्र का उपयोग करते हुए,
HM =
हम जानते हैं कि,
(αβ) = c/a =
(α + β) = −b/a =
योग और गुणनफल के मानों को समीकरण (1) में रखने पर,
