Question

x+1/x=0 please solve ​

Answer 1

Given

⠀

$\large{\tt{\longmapsto{\dfrac{x + 1}{x} = 0}}}$

⠀

Solution

• Let do it with step by step.

⠀

★ Multiplying x both the side

$\large{\tt{\longmapsto{\dfrac{x + 1}{\cancel{x}} \times \cancel{x} = 0 \times x}}}$

⠀

$\large{\tt{\longmapsto{x + 1 = 0}}}$

⠀

★ Subtracting 1 both the side

$\large{\tt{\longmapsto{x + 1 - 1 = 0 - 1}}}$

⠀

$\large{\tt{\longmapsto{x = -1}}}$

⠀

• Value of x is -1

Answer 2

Answer:

We have to get 3 here. Consider (+4) and (-1) as the factors, whose multiplication is -4 and sum is 3. Hence, we write x2 + 3x – 4 = 0 as x2 + 4x – x – 4 = 0. Thus, we can factorise the terms as: (x+4)(x-1) = 0. For any two quantities a and b, if a×b = 0, we must have either a = 0, b = 0 or a = b = 0.

Thus we have either (x+4) = 0 or (x-1) = 0 or both are = 0. This gives x+4 = 0 or x-1 = 0. Solving these equations for x gives: x=-4 or x=1. This method is convenient but is not applicable to every equation. In those cases, we can use the
