Find one value of xxx that is a solution to the equation (2x+3) 2 −6x−9=0

vesna_86 [32]

(2x+3) ^2 −6x−9=0

(2x+3) (2x+3) −6x−9=0

Foil

4x^2 +6x+6x+9-6x-9=0

4x^2 +12x+9-6x-9=0

Combine like terms

4x^2 +6x=0

factor out 2x

2x(2x+3)=0

2x=0 2x+3=0

x=0 2x=-3

x=-3/2

Answer x=-3/2, 0

Item 2

Inessa05 [86]

The question is an illustration of a division model.

The boxes will be completed with: 1650, 231, 50 and 7

The expression is represented as:

$\mathbf{1881 \div 33}$

Express 1881 as 1650 + 231.

$\mathbf{1881 \div 33 = (1650 + 231) \div 33}$

Split

$\mathbf{1881 \div 33 = 1650 \div 33 + 231 \div 33}$

Evaluate each division

$\mathbf{1881 \div 33 = 50 + 7}$

$\mathbf{1881 \div 33 = 57}$

The above illustration means that, the boxes will be completed with the following numbers

1650
231
50
7
