What are the solutions to X2 + 8X + 7 = 0?

Step-by-step explanation:

where a 0 so a = 1 b = 8 c = 7

Quadratic Formula:

    Evaluate the exponent and multiply 4ac

         Subtract b^2 - 4ac and multiply 2a

          Solve for the sqrt root of 35

x = - 8 ± 6/2 =

x = - 8 + 6/2 = -1

x = - 8 - 6/2 = -7

step-by-step explanation:

1-16

2-32

4-64

8-128

all multiples of 16

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
