Mathematics Formula In Hindi
गणित सूत्र आपके आने वाले सभी प्रतियोगी परीक्षाओं जैसे SSC CGL, SSC CHSL, Bank Exams, Railway, Delhi police, Patwar, UPPSC, MPPSC, RPSC, Defense और भी सभी प्रतियोगी परीक्षाओं के लिए बेहद उपयोगी साबित होने वाली है | जैसा कि आप सभी को पता है मैथ केवल फार्मूला से ही सॉल्व हो सकता है आते हमें फार्मूले याद होंगे तभी हम मैथ की प्रॉब्लम्स को सॉल्व कर पाएंगे यह पीडीएफ आपके लिए बहुत ही महत्वपूर्ण है.
Algebra Math Formula (बीजगणित सूत्र)
यदि हमें बीजगणित गणित के सूत्र नहीं पता है तो बीजगणित सबसे कठिन साबित हो सकती है और यदि हमें बीजगणित के सभी सूत्र याद है तो बीजगणित सबसे सरल है और एक स्कोरिंग सब्जेक्ट है तथा इससे हम सभी बीजगणित की प्रॉब्लम्स को आसानी से सॉल्व कर सकते हैं आते इस पारा में हम आपको आज बीजगणित के सभी सूत्र बतायेंगे .
- a2 – b2 = (a – b)(a + b)
- (a+b)2 = a2 + 2ab + b2
- a2 + b2 = (a – b)2 + 2ab
- (a – b)2 = a2 – 2ab + b2
- (a + b + c)2 = a2 + b2 + c2 + 2ab + 2ac + 2bc
- (a – b – c)2 = a2 + b2 + c2 – 2ab – 2ac + 2bc
- (a + b)3 = a3 + 3a2b + 3ab2 + b3 ; (a + b)3 = a3 + b3 + 3ab(a + b)
- (a – b)3 = a3 – 3a2b + 3ab2 – b3
- a3 – b3 = (a – b)(a2 + ab + b2)
- a3 + b3 = (a + b)(a2 – ab + b2)
- (a + b)3 = a3 + 3a2b + 3ab2 + b3
- (a – b)3 = a3 – 3a2b + 3ab2 – b3
- (a + b)4 = a4 + 4a3b + 6a2b2 + 4ab3 + b4)
- (a – b)4 = a4 – 4a3b + 6a2b2 – 4ab3 + b4)
- a4 – b4 = (a – b)(a + b)(a2 + b2)
- a5 – b5 = (a – b)(a4 + a3b + a2b2 + ab3 + b4)
- If n is a natural number :- an – bn = (a – b)(an-1 + an-2b+…+ bn-2a + bn-1)
- If n is even :- (n = 2k), an + bn = (a + b)(an-1 – an-2b +…+ bn-2a – bn-1)
- If n is odd :- (n = 2k + 1), an + bn = (a + b)(an-1 – an-2b +…- bn-2a + bn-1)
- (a + b + c + …)2 = a2 + b2 + c2 + … + 2(ab + ac + bc + ….)
- Laws of Exponents :- (am)(an) = am+n (ab)m = ambm (am)n = amn
- Fractional Exponents :- a0 = 1 aman=am−n am = 1a−m a−m = 1am
- Roots of Quadratic Equation :-
- For a quadratic equation ax2 + bx + c where a ≠ 0, the roots will be given by the equation as −b±b2−4ac√2a
Δ = b2 − 4ac is called the discrimination - For real and distinct roots, Δ > 0
- For real and coincident roots, Δ = 0
- For non-real roots, Δ < 0
- If α and β are the two roots of the equation ax2 + bx + c then, α + β = (-b / a) and α × β = (c / a).
- If the roots of a quadratic equation are α and β, the equation will be (x − α)(x − β) = 0
- Factorials :-
n! = (1).(2).(3)…..(n − 1).n
n! = n(n − 1)! = n(n − 1)(n − 2)! = ….
0! = 1
(a+b)n=an+nan−1b+n(n−1)2!an−2b2+n(n−1)(n−2)3!an−3b3+….+bn,where,n>1
