we are given
quadratic equation as
now, we can find b and c from
we can see that coefficient of x^2 is 1
so, we will have to make coefficient x^2 as 1
so, we divide both sides by 3
now, we can simplify it
now, we can compare it with
we get
so, we get order pair as

Answer:
Area of the composite figure = 75.25 cm²
Step-by-step explanation:
Question (4). Given figure is a composite figure having,
(1). Right triangle STU
(2). A kite PSUV
(3). A trapezoid PQRS
Now we will calculate the area of each figure.
(1). Area of the right triangle =
=
= 5.25 cm²
(2). Area of the kite PSUV =
=
=
= [Since SV = 2 × 3 = 6 cm]
=
= 31.5 cm²
(3). Area of the trapezium = [Where and are the bases and h is the distance between the bases]
=
=
= 38.5 cm²
Total area of the given figure = 5.25 + 31.5 + 38.5
= 75.25 cm²
