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).

Translate the sentence into an equation.
4vir4ik [10]

The translation of the given sentence into an equation is: 7(b + 3) = 1.

<h3>How to Translate a Sentence into an Equation?</h3>

Variables can be used to represent an unknown quantity when translating statements into equation. The word "times" is represented as or means "×" (multiplication). "Sum" means addition as well.

Thus, the sentence given can be translated as shown below:

The unknown number is represented as variable b.

"The sum of a number (b) and 3" would be translated as: b + 3.

"Seven (7) times the sum of a number and 3 (b + 3)" would therefore be: 7(b + 3).

Therefore, translating the whole sentence into an equation, we would have:

7(b + 3) = 1.

Thus, the translation of the given sentence into an equation is: 7(b + 3) = 1.
