The function h(x) is defined by the expression x2 - 4x + 3. Use factoring
1 answer:
Answer:
The zeros are x = 1 and x = 3
In the picture attached, the graph of the function is shown. The zeros are those points where h(x) intersect x-axis.
Step-by-step explanation:
Given the expression:
x² - 4x + 3
Rewrite -4x term:
x² - x - 3x + 3
Take x as common factor in the first terms, and -3 in the last terms:
x(x - 1) - 3(x - 1)
Take (x - 1) as common factor:
h(x) = (x - 1)(x - 3)

Answer:
Therefore,
The length of the sides of the squares is
Step-by-step explanation:
Let "x" be the length of Cut Square,
As the tin size(Dimension) is
20 cm × 50 cm
So the size(Dimension) of box will be
(20 - 2x) × (50 - 2x)
Length = 50 - 2x
Width = 20 - 2x
Area of base of box = 216 cm²
To Find:
x = ?
Solution:
Area of Rectangular field is given by
Substituting the values we get
Applying Distributive property we get
Dividing throughout by 4 we get
On Factorizing we get
As x cannot be 28 because tin size is 20 cm × 50 cm i.e longer than 20
Therefore,
Therefore,
The length of the sides of the squares is
