Which value of "X" is a solution to this equation? 4x2 +22x +10

Mathematics
1 answer:
Maslowich2 years ago
5 0

Answer:

Two solutions: X = -5 and X = -0.5

Step-by-step explanation:

4x^2 + 22x + 10 = 0 // divide by 2

2x^2 + 11x + 5 = 0

delta = 11^2 - 4 * 2 * 5 = 121 - 40 = 81

sqrt(delta) = 9

x1 = (-11 - 9) / 4 = -5

x2 = (-11 + 9) / 4 = -0.5

Solve the simultaneous equation:<br> 2x - y= 2<br> 3y= 4x - 5
Ronch [10]

Answer:

x = \frac{1}{2} , y = -1

<u>Explanation</u>:

2x - y= 2

3y= 4x - 5

<u>Make y the subject:</u>

2x - y= 2

-y = 2 - 2x

y = 2x - 2  <em>.........equation 1 </em>

3y= 4x - 5

y = (4x - 5)/3<em> ........equation 2</em>

From equation 1 and 2 solve them simultaneously:

→ (4x - 5)/3 =  2x - 2

→ 4x - 5=  3(2x - 2)

→ 4x - 5 = 6x - 6

→ 6x - 4x = -5 + 6

→ 2x = 1

→ x = 1/2

  • if x is 1/2, then y: 2x - 2

                              →  2(1/2)-2

                              →  -1
