Step-by-step solution

4 steps

यहाँ दिए गए व्यंजकों को घटाना है: (5a2−2a)(5a^2 - 2a) में से (7a2+5a+6)(7a^2 + 5a + 6) घटाएँ।

  1. घटाने के लिए व्यंजक लिखें।

    (5a2−2a)−(7a2+5a+6)(5a^2 - 2a) - (7a^2 + 5a + 6)
  2. दूसरे कोष्ठक के अंदर के प्रत्येक पद पर ऋण चिह्न वितरित करें।

    5a2−2a−7a2−5a−65a^2 - 2a - 7a^2 - 5a - 6
  3. समान पदों को एक साथ समूहित करें।

    (5a2−7a2)+(−2a−5a)−6(5a^2 - 7a^2) + (-2a - 5a) - 6
  4. समान पदों को संयोजित करें।

    (5−7)a2+(−2−5)a−6(5-7)a^2 + (-2-5)a - 6 −2a2−7a−6-2a^2 - 7a - 6
