Step by step plz <br> 2x^2 + x - 3
Aleks04 [339]

Answer:

x = 1 or x = -3/2

Step-by-step explanation:

Solve for x over the real numbers:

2 x^2 + x - 3 = 0

The left hand side factors into a product with two terms:

(x - 1) (2 x + 3) = 0

Split into two equations:

x - 1 = 0 or 2 x + 3 = 0

Add 1 to both sides:

x = 1 or 2 x + 3 = 0

Subtract 3 from both sides:

x = 1 or 2 x = -3

Divide both sides by 2:

Answer: x = 1 or x = -3/2

What is the value of n? n–2= 10n+ 4/2 Enter your answer in the box.
pentagon [3]

Answer:

-4 / 9

Step-by-step explanation:


 n - 2 = 10n + 4/2

 n - 10n = 4/2 + 2

 -9n = 4/2 + 4/2 ( taking LCM of 4/2 and 2)

 -9n = 8/2

 -9n = 4

    n = 4 / -9

   

   therefore n = -4 /9 ( since the minus sign doesn't make a difference whether placed at numerator or denominator) .
