19. A quadratic equation is shown below.

victus00 [196]

Answer:

$\{\sqrt b, -\sqrt b\}$

Step-by-step explanation:

Given

$a^2 - b = 0$

Required

Determine the solution

Since b is a perfect square, the equation can be expressed as:

$a^2 - (\sqrt b)^2 = 0$

Apply difference of two squares:

$(a - \sqrt b)(a + \sqrt b) = 0$

Split:

$(a - \sqrt b)= 0 \ or\ (a + \sqrt b) = 0$

Remove brackets:

$a - \sqrt b= 0 \ or\ a + \sqrt b = 0$

Make a the subject in both equations

$a =\sqrt b \ or\ a =-\sqrt b$

The solution can be represented as:

$\{\sqrt b, -\sqrt b\}$

hawnda incorrectly found the distance between -26 and 25 by following these steps: Step 1: |25 – (-26)| Step 2: |25 – 26| Step 3

tekilochka [14]

Answer:

Step 2

Step-by-step explanation:

Step 2 is not correct. It should be abs(25 - - 26) = abs(25 + 26) = 51

Given that Step 2 is accepted (as - 1) then three is OK and and so is 4. But technically they are incorrect as well. I think you are likely to say that step 2 is the problem.

LenKa [72]

Y=5/4x-4
5/4 is the slope but to pass through the point it needs to cross the y axis at -4
