3. if kx² + 2x + k = -kx have equal roots, find the values of k.<br>​
crimeas [40]

Answer:

k = - \frac{2}{3} , k = 2

Step-by-step explanation:

Using the discriminant Δ = b² - 4ac

The condition for equal roots is b² - 4ac = 0

Given

kx² + 2x + k = - kx ( add kx to both sides )

kx² + 2x + kx + k = 0 , that is

kx² + (2 + k)x + k = 0 ← in standard form

with a = k, b = 2 + k and c = k , thus

(2 + k)² - 4k² = 0 ← expand and simplify left side

4 + 4k + k² - 4k² = 0

- 3k² + 4k + 4 = 0 ( multiply through by - 1 )

3k² - 4k - 4 = 0 ← in standard form

(3k + 2)(k - 2) = 0 ← in factored form

Equate each factor to zero and solve for k

3k + 2 = 0 ⇒ 3k = - 2 ⇒ k = - \frac{2}{3}

k - 2 = 0 ⇒ k = 2

Please I need answers Factorize x²-6x+9
miskamm [114]

Answer:

The factors of the given equation are:

x^2-6x+9=(x-3)(x-3)=(x-3)^2

Step-by-step explanation:

We have :

x^2-6x+9

Using middle term splitting theorem to factorize the expression :

x^2-3x-3x+9

x(x-3)+(-3)(x-3)

(x-3)(x-3)

x^2-6x+9=(x-3)(x-3)=(x-3)^2

The factors of the given equation are:

x^2-6x+9=(x-3)(x-3)=(x-3)^2
