Question

pls solve it because tomorrow is my exam​

Answer 1

Answer:

x= 2b/a or x=b/a

Step-by-step explanation:

divide theequation by a^2

=x^2-3bx/a+2b^2/a

=x^2-2(3b/2a)+2b^2/a^2

adding and subtraction (3b/2a)^2

=x^2-2x(3b/2a)+(3b/2a)^2-(4b/2a)^2+2b^2/a^2

=(x-3b/2a)^2-ab/4a^2+2b^2/a^2

=(x-3b/2a)^2+-9b^2+8b^2/4a^2

=(x-3b/a2a)^2-b2/4a^2

=(x-3b/2a)^2=b^2 /4a^2

=x-3b/2a=plusminusb/2a

if x=+b/2a                               |               if x=-b/2a

x=3b/2a+b/2a                        |               x=3b/2a-b/2a

x=4b/2a                                  |               x=2b/2a

x=2b/a                                    |               x=b/a
