Which expression is a factor of 10x^2+11x+3

Mathematics
1 answer:
Ulleksa [173]3 years ago

Answer:

The factors are (5x + 3) and (2x + 1)

Step-by-step explanation:

When you need to factor a quadratic, and the coefficient of the x² is not 1, use the slide and divide method.

The general form of a quadratic is ax² + bx + c

Factor:  10x² + 11x + 3

Here a = 10, b = 11, and c = 3

Step 1:  Multiply ac, we SLIDE a over to c.  Notice the 10 is gone for now..

    x² + 11x + 30

Step 2:    Factor this   (this step will always factor)

  x² + 11x + 30 = (x + 5)(x + 6)

So the factors are  (x + 5)(x + 6), but we now need to DIVIDE by a, since we multiplied it into c before.  We divide the constants in the factors...

   (x + 5/10 )(x + 6/10 )  

Now reduce the fractions as much as possible...

(x + 1/2 )(x + 3/5)

*If they don't reduce to a whole number, SLIDE the denominator over as a coefficient of x....

(2x + 1)(5x + 3)        *2 slide over in front of x, 5 slide over in front of x, the fractions are gone!

These are our factors!

Find the distance between the complex numbers. z1 = 9 - 9i z2 = 10 - 9i
steposvetlana [31]

Answer:

The distance between the two given complex numbers = 9

Step-by-step explanation:

<u><em>Explanation</em></u>:-

<u><em>Step(i):</em></u>-

Given  Z₁ = 9 - 9 i    and Z₂ = 10 -9 i

Let A and B represent complex numbers Z₁ and Z₂ respectively on the argand plane

⇒ A =  Z₁ = x₁ +i y₁ = 9 - 9 i and

    B = Z₂ = x₂+ i y₂ = 10 -9 i

Let (x₁ , y₁) = ( 9, -9)

     (x₂, y₂) = (10, -9)

<u>Step(ii)</u>:-

<em>The distance between the two points are </em>

    A B   =   \sqrt{(x_{2} - x_{1})^{2}+(y_{2} - y_{1})^{2}    }

    A B =   \sqrt{(10 - 1)^{2}+(-9 - (-9))^{2}    }

   AB   = \sqrt{(9)^{2} +(-9+9)^{2} }

 <em> AB    =  √81 = 9</em>

<u><em>Conclusion:-</em></u>

The distance between the two given complex numbers = 9

<u><em></em></u>
