What are the solutions to the quadratic equation 0=(x−4)(x+2)?

Alex777 [14]

Answer:

x = 4,

x = -2

Step-by-step explanation:

( x - 4 ) ( x + 2 ) = 0

Find out when the equation is 0,

When x = 4,

substitute in 4 for x,

( 4 - 4 ) ( 4 + 2 ) = 0

(0) ( 6) = 0 (any number multiplied by 0 is 0).

When x = -2

Substitue in -2 for x,

( -2 - 4 ) ( -2 + 2 ) = 0

(-6) (0) = 0 (again, any number multiplied by 0 is 0).

Simplify the expression: 3x (4x-6) ————— 2x(3x)

Marina86 [1]

Answer:

$=\frac{2x-3}{x}$

Step-by-step explanation:

$=6x^2\\\mathrm{Remove\:parentheses}:\quad \left(a\right)=a\\=\frac{3x\left(4x-6\right)}{2x\cdot \:3x}\\2x\cdot \:3x=6x^2\\=\frac{3x\left(4x-6\right)}{6x^2}\\\mathrm{Cancel\:}\frac{3x\left(4x-6\right)}{6x^2}:\quad \frac{4x-6}{2x}\\=\frac{4x-6}{2x}\\\mathrm{Factor}\:4x-6:\quad 2\left(2x-3\right)\\=\frac{2\left(2x-3\right)}{2x}\\\mathrm{Divide\:the\:numbers:}\:\frac{2}{2}=1\\=\frac{2x-3}{x}$
