Question

6(5x + 1) + x2 = (x + 1)(x + 2)​

Answer 1

6(5x + 1) + x2 = (x + 1)(x + 2)

30x+6+x² = x²+3x+2

30x+6 = 3x+2

30x-3x = 2-6

27x = -4

x = -4/27

Answer 2

Answer:

Step-by-step explanation:

6(5x + 1) + x² = (x + 1)(x + 2)​

⇒ 30x + 6 + x² = x ( x +2 ) + 1 ( x + 2 )

⇒ 30 x + 6 + x² = x² + 2x + x + 2

⇒ 0 = x² - x² + 3x - 30 x + 2 - 6

⇒ 0 = - 27x - 4

⇒ + 4 = -27 x

⇒ 4 / -27 = x

⇒ x = - 4 / 27
