Simplify completely quantity 2 x squared plus 16 x plus 30 all over quantity 5 x squared plus 13 x minus 6

Answer 1

for nominator I got 2(x^2+8x+15) but idk how to get the denominator..

Answer 2

for the denominator it can be factored :
(5x - 2)(x + 3)
now can you factor out the numerator ?

Answer 3

no I'm so lost, how did you even get that?

Answer 4

2 open parentheses x plus 5 close parentheses over quantity 5 x minus 2
is this the answer?

Answer 5

5x^2 + 13x - 6

factor of 5x^2 is 5x times x
so, 5x^2 + 13x - 6 = (5x .... )(x .....)

factor of -6 = -2 * 3 or 2 * -3
i choice -2 * 3 to fill ..... in parantheses above
so, it is (5x - 2)(x + 3). because if you expand it would becomes back to
5x^2 + 13x - 6

Answer 6

is my answer wrong?

Answer 7

i dont know (yet), before you write the factor of numerator

Answer 8
