Answer:
x= -7/8
Step-by-step explanation:
8x + 7 = 0
8x + 7-7 = 0-7
8x=-7
8x/8x = -7/8
Answer:
no solution
Step-by-step explanation:
use the box method to find out the factors
| 7
x^2 |
the top left and top right must multiply to 7x^2 and add up to 6x.
7 is multiplied together by 7 and 1, but only 7 and -1 can add up to 6x, so therefore there is no solution to this equation
another way is the quadratic equation
for an equation in form ax^2 +bx + c,
the quadratic equation states x = (-b + square root(b^2-4ac))/2a
in this case : x = -6 + (6^2 -28)^1/2 = -6+ (some negative root that doesn't exist)
so x = no solution
