Answer:
To determine the nature of roots of quadratic equations (in the form ax^2 + bx +c=0) , we need to calculate the discriminant, which is b^2 - 4 a c. When discriminant is greater than zero, the roots are unequal and real. When discriminant is equal to zero, the roots are equal and real.
Answer:

Step-by-step explanation:
(x-1)^2=9 <=> x-1=3 <=> x=4
40+90=130
180-130=50
50+130=180
x=130
50+x=180
