Question

`If the equation 4x^2 - 2 (k + 1) + (k + 1) = 0 Find the value of k.​

Answer 1

Answer:

Step-by-step explanation:

to find the value of k  4x² - 2(k + 1) + (k + 1) = 0

first we divide both side by 4

⇒ x² - 2/4(k + 1) + 1/4(k + 1) = 0

 x² = 1/2(k + 1) - 1/4(k + 1)

 x² = k/2 + 1/2 - k/4 - 1/4

x² = k/2 - k/4 + 1/2 - 1/4

 x² = k/4 + 1/4

 ⇒ x² - 1/4 = k/4

 then we multiply both side by 4

⇒ 4(x² - 1/4) = k

 k = 4(x² - 1/4)
