Juliet decided to solve the quadratic x2 + 8x = 9. Which of the following steps is where she made her first mistake? x2 + 8x = 9 Step 1: x2 + 8x − 9 = 0 Step 2: (x + 9)(x − 1) = 0 Step 3: x = 9 and x = -1

Step-by-step explanation:

hello

last step is not good

from

(x+9)(x-1) = 0 we can write

<=> x+9 = 0 or x-1=0

<=> x = -9 or x = 1

so the solutions are -9 and 1

hope this helps

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
