Δ = (8i)^2 - 4*(-25) => Δ = -36 +100 => Δ = 64 => x1 =(-8i + 8)/2 => x1 = -4i +4;
x2 = (-8i - 8)/2 => x2 = -4i-4; in this case, your solutions are complex conjugates.
Dont know im sorry i dont find the pattern
30, i don’t have the explanation i just remember this equation from Algebra 2 for some odd reason
1&14 2&7 7&2 14&1 the factor pairs are all the expressions you can make that equal 14. I hope that will help you with future problems.
