roots 12-5x-4kx

roots

12 - 5 x - 4 k x

x = \frac{12}{5 + 4 k}; k \neq = - \frac{5}{4}

Solution steps

12 - 5 x - 4 k x

The roots are the intercepts with the x-axis

(y = 0)

12 - 5 x - 4 k x = 0

Move

12

to the right side

- 5 x - 4 k x = - 12

Factor

- 5 x - 4 k x : - x (5 + 4 k)

- x (5 + 4 k) = - 12

Divide both sides by

- (5 + 4 k); k \neq = - \frac{5}{4}

x = \frac{12}{5 + 4 k}; k \neq = - \frac{5}{4}

f (x) = \frac{x ^{2} \cdot 4 \cdot π ^{2} - x ^{2}}{24 \cdot π ^{2}}

f (x) = lo g_{2} (8)

f (x) = 4 x^{2} + 5 x + 6

P (x) = 4 x^{5} - 8 x^{4} - 61 x^{3} + 146 x^{2} + 15 x - 36

y = 14 - x
