Question

solve by factorization.3x²-x=8​

Answer 1

3x^2-x-8=0

Use the quadratic formula

a=3,b=-1,c=-8

x=-b+or-root of b^2-4ac/2a

=-1 + or - root of -1^2-4(3)(-8)/2(3)

=1 +or -root 97/6

=1+or-9.848/6

=10.848/6=1.808

=-8.848/6=-1.4746

i hope this helps

${\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\pink{ANSWER}}}}}}}}$

${3x}^{2} - x = 8 \\ {3x}^{2} - x - 8 = 0$

$\red{\boxed{\boxed{\purple{x = \frac{ - b + \sqrt{ {b}^{2} } + - 4ac } \pink{2a} \: }}}} \: \\ {3x}^{2} −−8=0 \\ a = 3 \\ b = - 1 \\ c = - 8 \\ \\ </p><p></p><p></p><p></p><p></p><p></p><p></p><p></p><p></p><p>$
