5xt3y=5 State the root
A) 1.0)
)
b. C2, 1) C. C-1,-2) d.(0.1)​

Answer 1

Answer:

A)1.0 is the correct answer

Answer 2

Answer:

$\pink{\bold{\underline{Answer}}}$

Let us consider,

The breadth of the rectangular plot is x m.

Thus, the length of the plot = (2x + 1) m

As we know,

Area of rectangle = length × breadth = 528 m2

Putting the value of length and breadth of the plot in the formula, we get,

(2x + 1) × x = 528

⇒ 2x2 + x = 528

⇒ 2x2 + x – 528 = 0

Hence, 2x2 + x – 528 = 0, is the required equation which represents the given situation.

There can be one or more than one solution. These are called the roots of the quadratic equation. For a quadratic equation ax2+bx+c = 0, the sum of its roots = –b/a and the product of its roots = c/a.
