What is the solution of the equation (x – 5)2 + 3(x – 5) + 9 = 0? use u substitution and the quadratic formula to solve. x = 2 x = 8

For this case we have the following equation:

We make the following change of variables:

We have then:

Then, using the quadratic formula we have:

Solution 1:

Solution 2:

Finally, returning the change we have:

Solution 1:

Solution 2:

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
