The missing step that Sarah has to write as the result of Step 1 will be 2(x + 1)² = 128.
The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The equation is given below.
2(x + 1)² + 6 = 134
Simplify the equation, then we have
2(x + 1)² + 6 = 134
2(x + 1)² = 128
(x + 1)² = 128 / 2
(x + 1)² = 64
Take square root on both sides. Then we have
(x + 1) = ± 8
x = - 1 ± 8
x = - 1 - 8, - 1 + 8
x = - 9, 7
The missing step that Sarah has to write as the result of Step 1 will be 2(x + 1)² = 128.
