yeah how do you do that

Answer 6

Nolan come back

Answer 7

distribute the two binomials first.
(2x+1)(x-1)
AND YOU'LL GET 2x^2-2x+x-1 which is 2x^2-x-1 after combining like terms

2x^2-x-1=14
subtract 14 both side and you'll get
2x^2-x-15=0

factor the function, solve for x and there are your answers.
hope this help...
