Question

if the roots of the polynomial
(p)= 3x²-3x+13m-9 are inverse to each other then find tje value of m.​

Answer 1

Answer:

4.1 Introduction

4.1.

4-1

Fig. 4.1

Now, area of the hall = (2x + 1). x m2 = (2x2 + x) m2

So, 2x2 + x = 300 (Given)

Therefore, 2x2 + x – 300 = 0

So, the breadth of the hall should satisfy the equation 2x2 + x – 300 = 0 which is a quadratic equation.

Answer 2

Explanation:

Answer:

\large{\underline{\underline{{\sf{\purple{Given \:Equations:-}}}}}}

GivenEquations:−

➨ 2x + 3y = -5

➨ x + y = -1

━━━━━━━━━━━━━━━━━━━━━

Putting the value of x = 0 in equation 2x + 3y = -5 :-

➨ 2(0) + 3y + 5 = 0

➨ y = \dfrac{-5}{3}

Putting the value of y = 0 in equation x + y = -1 :-

➨ x + 0 + 1 = 0

➨ x = -1

⚘ Their Coordinates are ( -1 , 0 )

Both lines intersect at a point (2 , -3).
