5x2 + (5p – 1)x – (2p + 5) या बहुपदीच्या शून्यांची बेरीज = 1/4 × शून्यांचा गुणाकार
वापरलेले सूत्र:
बहुपदीचे मानक रूप, ax2 + bx + c = 0
शून्यांची बेरीज = - b/a
शून्यांचा गुणाकार = c/a
गणना:
शून्यांची बेरीज = - (5p - 1)/5
शून्यांचा गुणाकार = - (2p + 5)/5
प्रश्नानुसार;
⇒ - (5p - 1)/5 = 1/4 × [- (2p + 5)/5]
⇒ (5p - 1) = (2p + 5)/4
⇒ 20p - 4 = 2p + 5
⇒ 20p - 2p = 5 + 4
⇒ 18p = 9
⇒ p = 9/18 = 1/2
∴ p ची किंमत = 1/2
