Question

Simplify (√3+2) (√3-2)

Answer 1

hey mate!

(√3+2)(√3-2)
that is (a+b)(a-b)=a^2-b^2
so, (√3+2)(√3-2)=√3^2-2^2
=3-4=-1

Answer 2

Concept

The polynomial equations of degree two in one variable of form f(x) = ax2 + bx + c = 0 and with a, b, c, and R R and a 0 are known as quadratic equations. It is a quadratic equation in its general form, where "a" stands for the leading coefficient and "c" for the absolute term of f. (x).

Given

The equation given is  (√3+2) (√3-2)

Find

We need to Simplify (√3+2) (√3-2)

Solution

The given equation  (√3+2) (√3-2) is in the form of general equation (a+b)(a-b)

Now we know that a^2-b^2 = (a+b)(a-b)

Applying the formula We get

(√3)^2-(2)^2 = 3-4

= -1

Hence the simplification is -1
