Question

23.Obtain all the zeros of 3x7x

6,−+if one of its zeroes is ​

Answer 1

Answer:

Step-by-step explanation:

Hi friend,

given polynomial,

x³-7x+6

One of the zero is 1,means

(x-1) is a factor of x³-7x+6

Divide x³-7x+6 by (x-1),

we get x²+x-6

x³-7x+6=(x-1)(x²+x-6)

x³-7x+6=(x-1)(x²-2x+3x-6)

x³-7x+6=(x-1)(x(x-2)+3(x-2))

x³-7x+6=(x-1)(x-2)(x+3)

The other two factors are (x-2) and (x+3)

So, the other two zeroes of the given polynomial are 2 and -3.

hope it helps

Answer 2

Answer:

Water and minerals are transported in plants with the help of xylem tissue. Roots absorb the water from the soil by actively taking up ions, creates the difference in the concentration of these ions between the root and the soil. ... The water loss by leaves through stomata is called transpiration.
