Question

solve quadratic equation by factorization method y2 -3=0

Answer 1

Given,

A quadratic equation y²-3 = 0

To Find,

The solution this equation.

Solution,

The given quadratic equation is y²-3 = 0

By using the factorization method

y²-√3² = 0

Now, using the formula a²-b² = (a+b)(a-b)

where a = y and b= √3

So,

(y+√3)(y-√3) = 0

y = -√3 or √3

Hence, the solution of y²-3 = 0 is y = √3 or -√3.

Answer 2

Answer:

Step-by-step explanation:

Given,

A quadratic equation y²-3 = 0

To Find,

The solution this equation.

Solution,

The given quadratic equation is y²-3 = 0

By using the factorization method

y²-√3² = 0

Now, using the formula a²-b² = (a+b)(a-b)

where a = y and b= √3

So,

(y+√3)(y-√3) = 0

y = -√3 or √3

Hence, the solution of y²-3 = 0 is y = √3 or -√3.
