Given:

$y^{2}(2 y-5)-8 y+20$

To find:

The product of the expression.

Solution:

$y^{2}(2 y-5)-8 y+20=y^{2}(2 y-5)+(-8 y+20)$

Take out -4 as a common factor in Last two terms.

$=y^{2}(2 y-5)-4(2 y-5)$

Make sure the terms in both brackets must be same.

Take out common factor (2y - 5) from both terms.

$=(2 y-5)(y^{2}-4)$

4 can be written as 2².

$=(2 y-5)\left(y^{2}-2^2\right)$

Using the identity: $(a^2-b^2)=(a-b)(a+b)$

$=(2 y-5)(y-2)(y+2)$ .

The product is $(2 y-5)(y-2)(y+2)$ .

Subtract 2 from 20. Then, divide 18 by 3 and that should give you 6.

What are the lower bound estimate and the upper bound estimate found by rounding to the greatest place?

vovangra [49]

Greatest place is the hundreds place so 800 - 200 = 600
Or 760 - 240 = 520 you can round the 520 to 500
Upper and lower bounds accordingly
So 600 and 500.
