Question

simplify (3+2root2)(3-2 root 2)​

Answer 1

here we can apply the formula (a+b)(a-b)=a^2-b^2

here a=3

b=2root 2

(3+2 root2)(3-2root2)

3^2-(2root2)^2=9-8=1

Hence problem solved

Answer 2

Answer: 7.59

Step-by-step explanation:

Given : (3+2root2)(3-2 root 2)​

Assuming a = 3 b = $2\sqrt{2}$

Then using formula for (a+b) (a-b) we get $a^{2} - b^{2}$

Hence $3^{2} - 2\sqrt{2} x^{2}$

= 9 - 1.41

= 7.59

Answer = 7.59

Algebra Formulas are the cornerstone of many mathematical concepts. For comprehending and solving difficult issues, topics such as equations, quadratic equations, polynomials, coordinate geometry, calculus, trigonometry, and probability heavily rely on algebra formulae. Algebraic formulae are useful for doing complex computations in the shortest amount of time and with the fewest steps. An algebraic formula is a rule or equation stated in mathematical and algebraic symbols. It's an equation with algebraic expressions on both sides. The algebraic formula is a brief formula used to do difficult algebraic problems.
