Question

Will mark Brainiest solve any of them.

Answer 1

Answer:

Q4. -2, 10

Step-by-step explanation:

$\frac{x}{x-5} = \frac{4}{x-4}$

By taking LCM,

x(x-4) = 4(x-5)

$x^{2}$ - 4x = 4x - 20

$x^{2}$ - 8x + 20 = 0

$x^{2}$ + 2x - 10x + 20 = 0

x(x +2 ) - 10 (x +2) = 0

(x+2) (x- 10) = 0

x = -2, 10

Answer 2

Answer:

3.

${x}^{2} - 14x + 3x - 42 \\ x(x - 14) + 3(x - 14) \\ (x - 14)(x + 3)$

4.

${x}^{2} - 4x = 4x - 20 \\ {x}^{2} - 8x + 20 \\ {x}^{2} + 10x - 2x + 20 \\ x(x + 10) - 2(x + 10) \\ (x + 10)(x - 2)$
