Umm it doesnt come out for me!!!

Need two numbers whose product is 5*(-32)=-160 and sum is 6
16 and -10
so
5x^2 - 10x + 16x - 32 = 0
5x(x - 2) + 16(x - 2) = 0
(5x + 16)(x - 2) = 0
so
5x + 16 = 0 or x - 2 = 0
5x = -16 x = 2
x = -16/5
So the answer is x = -16/5 or x = 2
16 and -10
so
5x^2 - 10x + 16x - 32 = 0
5x(x - 2) + 16(x - 2) = 0
(5x + 16)(x - 2) = 0
so
5x + 16 = 0 or x - 2 = 0
5x = -16 x = 2
x = -16/5
So the answer is x = -16/5 or x = 2

Root(5x²+6x-32)
=root(5x²-10x+16x-32)
=root(5x(x-2)+8(x-2))
=root(5x+8)(x-2)
which is the final answer coz it will n't go further than this,
=root(5x²-10x+16x-32)
=root(5x(x-2)+8(x-2))
=root(5x+8)(x-2)
