Question

(2x²+16x+30)/(5x²+13-6) Simplify

Answer 1

can u factorize them ??

Answer 2

no im not really good at that

Answer 3

no probs..

Answer 4

2x²+16x+30

divide throughout by 2..

so, x2 + 8x + 15

the factors r 5 & 3... as 5 * 3= 15 and, 5 + 3 = 8

x2 + 5x + 3x + 15 = 0
x (x +5) + 3 (x +5) =0
(x + 5) (x + 3)..

can u try the same for other equation ??

Answer 5

yea

Answer 6

thank u

Answer 7

5x²+13-6
5x2 + 15x -2x - 6 = 0
5x (x +3) -2 (x +3) = 0
(5x -2 ) (x +3) = 0..

Now dividing both the equation, as given i question..

(x + 5) (x + 3) / (5x -2 ) (x +3 = (x +5) / (5x -2) .. is the answer..

Answer 8

@Ganpat , since u have divided it by 2, you need to multiply it again by 2
the factor for the numerator would be 2(x+5)(x+3)

Answer 9

oh yes.. my bad.. sorry.. it shd be multiplied back..

SO the answer = 2(x +5) / (5x -2)
