Step-by-step explanation:

Solution :-

1. Given equation is 4x²-11x = 7

=> 4x²-11x-7 = 0

The standard form = 4x²-11x-7 = 0

It is in the form of ax²+bx+c = 0

We have,

a = 4

b = -11

c = -7

2.Given equation is 5x² = 3x

=> 5x²-3x = 0

The standard form = 5x²-3x +0 = 0 or 5x²-3x = 0

It is in the form of ax²+bx+c = 0

We have,

a = 5

b = -3

c = 0

3.Given equation is (x+3)(x-2) = 1

=> x(x-2) +3(x-2) = 1

=> x²-2x+3x-6 = 1

=> x²+x-6 = 1

=> x²+x-6-1 = 0

=> x²+x-7 = 0

The standard form = x²+x-7 = 0

It is in the form of ax²+bx+c = 0

We have,

a = 1

b = 1

c = -7

4. Given equation is (x-7)²+3 = 0

=> x²-14x+49+3 = 0

=> x²-14x+52 = 0

The standard form = x²-14x+52 = 0

It is in the form of ax²+bx+c = 0

We have,

a = 1

b = -14

c = 52

5.Given equation is 6x² = 5x-4

=> 6x²-5x+4 = 0

The standard form = 6x²-5x+4 = 0

It is in the form of ax²+bx+c = 0

We have,

a = 6

b = -5

c = 4

a)

→ Transposing the terms form LHS to RHS

→ (a-b)² = a²-2ab+b²

→ When transposing the positive sign one side of other side in the equation then it becomes negative quantity.

→ When transposing the negative sign one side of other side in the equation then it becomes positive quantity.

→ Multiplication of terms in the equation.

b)

→ There is no difficulty to write the standard form of the equation .

→ It is easy to write in the form of ax²+bx+c = 0.
