X^2+16-38=0
find what 2 numbers multiply to get -38 and add to get 16
find factors of 38
2 times 19
there is no way to use common factor so use quadratic formula which is
x=

or x=

ax^2+bx+c=0 subsitte
a=1
b=16
c=-38
subsitute

=

=

=

=

so the answers for x are

and

which are aprox -2.099504938362 and +18.099504938362
so it would be
(x-[-8+√102])(x+[8+√102])=0

(2x - 1)(6x - 7)
2x(6x - 7) - 1(6x - 7)
2x(6x) - 2x(7) - 1(6x) + 1(7)
12x² - 14x - 6x + 7
12x² - 20x + 7
