गणितातील महत्वाची सूत्रे | IMP Mathamatical Equations for MPSC Exam

As we all know to Crack MPSC one should have good knowledge about CSAT. CSAT is the second paper for MPSC Prelim exam with equal mark weightage (200 Marks). Here are some (गणितातील महत्वाची सूत्रे) IMP Mathematical Equations for MPSC Exam which will help you to solve CSAT questions quickly. Knowing Mathematical Equations is a trick to score in maths questions.

• a×a = a2
• (a×b) + (a×c) = a (a+c)
• a × b + b= (a+1) × b
• (a+b)2 = a2 + 2ab + b2
• (a-b)2 = a2 + 2ab + b2
• a2-b2 = (a+b) (a-b)

• a2-b2 / a+b = a-b a2-b2/a-b = a+b
• (a+b)3 / (a+b)2 = a+b (a+b)3 / (a-b) = (a+b)2
• (a-b)3 / (a+b)2 = (a-b) (a-b)3 / (a-b) = (a+b)2
• a3 – b3 = (a-b) (a2 + ab+ b2)
• a × a × a = a3
• (a×b) – (a×c) = a (b-c)

• a × b- b = (a-1) × b ;
• a2 + 2ab + b2 / a+b = (a+b)
• a2 – 2ab + b2 / a-b = (a-b)
• (a+b)3 = a3 + 3a2b + 3ab2 + b3
• (a-b)3 = a3 – 3a2b + 3ab2 + b3
• a3 + b3 = (a+b) (a2-ab+b2)
• a3+b3 / a2-ab+b2 = (a-b)
