Algebra Formulas

This is horrifying…….

1}(a+b)²=a²+2ab+b² 2}(a-b)²=a²-2ab+b² 3}a²-b²=(a+b)(a-b) 4}(a+b)³= a³+3a²b+3ab²+b³ 5}(a-b)³= a³-3a²b+3ab²-b³ Using pascel triangle 6}(a+b)⁴=a⁴+4a³b+6a²b²+4ab³+b⁴ 7}(a-b)⁴=a⁴-4a³b+6a²b²-4ab³+b⁴ 8}(a+b)⁵= a⁵+5a⁴b+10a³b²+10a²b³+5ab⁴+b⁵ 9}(a-b)⁵= a⁵-5a⁴b+10a³b²-10a²b³+5ab⁴-b⁵ 10}(a+b)⁶=a⁶+6a⁵b+15a⁴b²+20a³b³+15a²b⁴+6ab⁵+b⁶ 11}(a-b)⁶=a⁶-6a⁵b+15a⁴b²-20a³b³+15a²b⁴ -6ab⁵+b⁶ 12} a³-b³=(a-b)(a²+ab+b²) 13}a³+b³=(a+b)(a²-ab+b²) 14}a⁴-b⁴=(a-b)(a³+a²b+ab²+b³) 15}a⁴+b⁴=(a+b)(a³-a²b+ab²-b³) .......... ♾️ you can 16}(a+b+c)²=a²+b²+c²+2(ab+bc+ca) 17}(a+b+c)³=a³+b³+c³+3(a+b)(b+c)(c+a) 18}(X+a)(X+b)=X²+(a+b)x+ab 19}(X+a)(X+b)(X+c)=X³+(a+b+c)x²+(ab+bc+ca)x+abc 20}a³+b³+c³-3abc=(a+b+c)(a²+b²+c²-ab-bc-ca) 21}(a+b+c) (ab+bc+ca) - abc = (a+b)(b+c)(c+a) 22} a²(b+c) + b²(c+a) +c²(a+b) + 2abc = (a+b)(b+c)(c+a) 23} bc(b+c) + ca(c+a) + ab (a+b) + 2abc = (a+b)(b+c)(c+a) 24}a(b²+c²)+b(c²+a²) + c(a²+b²) + 2abc = (a+b)(b+c)(c+a) 25}a²(b+c) + b²(c+a) + c²(a+b) + 3abc = (a+b+c)(ab+bc+ca) 26} bc(b+c) + ca(c+a) + ab(a+b) + 3abc = (a+b+c)(ab+bc+ca) 27}a(b²+c²) + b(c+a²) + c(a²+b²) + 3abc = (a+b+c)(ab+bc+ca)

(a+b)2=a2+2ab+b2 (a+b)2=a2-2ab+b2 (a+b)2+(a-b)2=2(a2-b2) (a+b)2+(a-b)2=4ab (x+a)(x-b)=x2+(a+b)x+ab (x+y+z)2=x2+y2+z2+2xy+2yz+2zx (x+a)(x+b)(x+c) =x3+(a+b+c)x2+(ab+bc+ca)x+abc (x+y)3=x3+3x2y+3xy+y3

Can you show example pls

It's very useful

It is very useful in mathematics❤🎉

Good ❤❤❤❤❤🎉🎉🎉🎉🎉🎉🎉

Thank you for your information

சூப்பர் அக்கா எனக்கு நல்ல புரிஞ்சுது

Math teachers master the whole book because my teacher doesn't use a book when explaining😮😮😮

So we meet again.. Old friend..

Good job

Smart people:oh i get it😊 me:😢😢😢huhhhhh wtf

It is a very good formulas in math

❤❤❤❤❤

Give us some example with this formulas❤❤❤❤❤

Good 👍😊💯☺️😌😃❤

What the helly My brain cannot comprehend no more and I’m cooked

College: Area of a Circle: \(A=\pi r^{2}\).Circumference of a Circle: \(C=2\pi r\).Area of a Triangle: \(A=\frac{1}{2}\times \text{base}\times \text{height}\).Pythagorean Theorem: \(a^{2}+b^{2}=c^{2}\).Area of a Rectangle: \(A=l\times w\). 3. Coordinate Geometry Formulas Slope of a Line: \(m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\).Distance Formula: \(d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\).Midpoint Formula: \(M=\left(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2}\right)\)
