Answer 2

Answer:

The value of x is 3,5

Step-by-step explanation:

Here we have been given to solve the following quadratic equation by the method of factorization. We will use the mid-term factorization method for getting the value of x in the above equation by factorizing the equation. We will proceed as below:

$x^{2} -8x + 15 = 0$

⇒ $x^{2} -(5+3)x+15 = 0$

⇒ $x^{2} - 5 x -3x +15=0$

⇒ $x(x-5) - 3(x-5) = 0$

⇒ $(x-3)(x-5)=0$

⇒ x = 3,5

Hence the value of x is 3 or 5 .
