Short Answer

Expert verified

The required value of b is52-3,-52-3

Step by step solution

01

Step 1. Given information

The equation:b2+6b=41

02

Step 2. Calculation

Solving the equation,

b2+6b=41

鈬�b2+6b+12脳62=41+12脳62

鈬�b2+6b+9=41+9

localid="1645259869172" 鈬�b2+6b+9=50

鈬�b2+3b+3b+9=50

鈬�b(b+3)+3(b+3)=50鈬�(b+3)(b+3)=50

localid="1645270880664" 鈬�(b+3)2=50鈬�b+3=卤52

localid="1645270913552" 鈬�b=卤52-3鈬�b=52-3,-52-3

The required value of bis localid="1645270951341" 52-3,-52-3
