Answer 2

Answer:

$\huge\blue{k = - 2x}$

Step-by-step explanation:

Q.

If (x² + k - 3) = (x - 3)(x + 1), then k = ?

.

Solution -

(x² + k - 3) = (x - 3)(x + 1)

=> x² + k - 3 = x (x + 1) - 3 (x + 1)

=> x² + k - 3 = x² + x - 3x - 3

=> x² + k - 3 = x² - 2x - 3

=> x² - x² + k - 3 + 3 = -2x

=> k = -2x

.

Hence the value of k = -2x
