Sarah solved a quadratic equation. Her work is shown below, with Step 1 missing.
What could Sarah have written as the result from Step 1?
2(x+1)^2+6=134
Step 1
(x+1)^2=64 Step 2
x+1=8 Step 3
x=-9 or x=7 Step 4
What is step 1?

step 1 - subtract 6 from both sides

Step-by-step explanation:

Given

2(x + 1)² + 6 = 134

Step 1 - subtract 6 from both sides

2(x + 1)² = 128

Step 2 - divide both sides by 2

(x + 1)² = 64

Step 3 - take the square root of both sides

x + 1 = ± = ± 8

Step 4 - subtract 1 from both side

x = - 1 ± 8

Step 5 - solve for x

x = - 1 - 8 = - 9 or x = - 1 + 8 = 7

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
