Question

solve equations by quadratic formula...​

Answer 1

Answer:

Step-by-step explanation:

x^2+2√2x+2

1). (-b+or-√b^2-4ac)/2a

b=2√2

a=1

c=2

(-2√2+or-√(2√2)^2-4×1×2)/2×1

-2√2+or-√8-8/2

-2√2/2=-√2

2).x^2-4√3x+12

a=1

b=-4√3

c=12

-b+or-√b^2-4ac/2a

-(-4√3)+or-√(-4√3)^2-4×1×12/2×1

4√3+or-√48-48/2

4√3/2
