Subtracting fractions with unlike denominators
lawyer [7]

Answer:

3/12 or simplified 1/4

Step-by-step explanation:

First make the denominators the same. We can make 12 the common denominator. To make 3/4 have a denominator do the following:

Multiply the numerator and denominator by 3 since 4x3=12. The new number becomes 9/12.

Then subtract:

9/12-6/12=3/12  The numerator subtracts while the denominator stays the same.

We can simplify 3/12 to 1/4

B) 2x² - 4x + 3 = 0<br> a) x² + 3x – 10 = 0
kozerog [31]

Answer:

a. x = 2 , x = -5

b. no real roots

Step-by-step explanation:

<u>a. x² + 3x – 10</u>

= x² - 2x + 5x - 10

= x (x²/x - 2x/x) + 5 (5x/5 - 2*5/5)

= (x - 2) (x + 5)

x - 2 = 0                            x + 5 = 0

 + 2    +2                             -5     -5

--------------                         ---------------

x = 2                                   x = -5

x = 2 , x = -5

<u>b. 2x² - 4x + 3 </u>

This can't be solved because the equation has no real roots, and also the discriminant is negative.
