Question

Find the roots of y2-2y+2=0 and 5 x 2 -27x+36=0 mahendra guru

Answer 1

Answer:

x2 + y2 = 36       (1)

x = 2y + 6          (2)

You can solve simulateous equations in three ways: Substitution, addition or subtraction. If one equation contains both x2 and y2 then you should use substitution as with this example.

1.) Substitute equation (2) into equation (1):

x = 2y + 6   therefore x2 = (2y + 6)2   so

(2y + 6)2 + y2 = 36
