What are the solutions of the quadratic equation (x – 8)2 – 13(x – 8) + 30 = 0? Use u substitution to solve. x = –11 and x = –18

Serggg [28]

Answer:

x=11 and x=18

Step-by-step explanation:

The given quadratic equation is;

$(x-8)^2-13(x-8)+30=0$

Let u=(x-8)

$u^2-13u+30=0$

Split the middle term;

$u^2-10u-3u+30=0$

Factor by grouping

$u(u-10)-3(u-10)=0$

$(u-10)(u-3)=0$

We have either u=10 or u=3

This implies that;

x-8=10 or x-8=3

x=10+8 or x=3+8

x=18 or x=11
