Answer 1

x1=-6/7 and x2=-7

Answer 2

So both of them are going to be negative ?

Answer 3

quad formula
x=[-b-+sqrtb^2-4ac]/2a

Answer 4

yes both negative.try that formula

Answer 5

Can you help on my other questions ?

Answer 6

7x^2+55x+42 =0
x=[-b-+sqrt(b^2-4ac)]/2a
x=[-55-+sqrt(55^2-4(7)(42))]/2(7)
x=[-55-+sqrt(3025-1176))]/14
x=[-55-+sqrt(1849))]/14
x=[-55-+sqrt(1849))]/14
x=[-55-+43)]/14
x1=-98/14=-7
x2=[-55+43)]/14=-12/14=-6/7
