Question

factorize 3x^2+13x-30 by completing square method

Answer 1

Answer:

Here's the answer:

3x^2+13x-30=0

=>3(x^2+13/3x-10)=0

=>(x)^2 + 2 × x × 13/6 + (13/6)^2 - (13/6)^2 - 10=0

=>(x+13/6)^2 - 169/36-10=0

=>(x+13/6)^2 - 529/36=0

=>(x+13/6)^2=529/36

=>x+13/6=√529/36

=>x=23/6 - 13/6

= 10/6 = 5/3

Therefore, x=+/- 5/3
