Question

find X if (2x+4) (4) = (4x-2) (X+1)​

Answer 1

Answer:

$(2x + 4)(4) = (4x - 2)(x + 1)$

$8x + 16 = 5x + 4x - 2x - 2$

$16 + 2 = 7x - 8x$

$18 = - x$

$x = - 8$

Hope it helps.

Answer 2

4(2x+4) = (x+1)(4x-2)

8x + 16 = $4x^{2}$ -2x + 4x - 2

$4x^{2}$ + 2x -8x - 2- 16 = 0

$4x^{2}$ - 6x -18 = 0

• use quadratic formula to solve it

x = $\frac{-b± \sqrt{b^{2}-4ac } }{2a}$

x = $\frac{-(-6)± √(-6)² - 4(4)(-18)}{2(4}$

x = 6± √36+288/8

x = 6+18/8 or 6-18/8

x = 3 or -1.5
