Gracias c:

Answer 1

2x(x-1)
=2x^2-2
3(2x-5)
=6x-15
2x^2-2-6x+15
=2x^2-6x+13

Answer 2

\[-b \pm \sqrt{b ^{2}-4ac}/2a\]

Answer 3

a=2,b=-6 and c=13
substitute the values

Answer 4

2x(x - 1) - 3(2x - 5)

2x(x) + 2x(-1) - 3(2x) - 3(-5)

2x^2 - 2x - 6x + 15

2x^2 - 8x + 15

Answer 5

oops i forgot that x
a=2 b=-8 c=15
