Question

2 (2a+3×) -3b-6x when a = -1 and b=2​

Answer 1

Step-by-step explanation:

We have,

a

2

−(2a+3b)

2

=(a−(2a+3b))(a+(2a+3b))∴a

2

−b

2

=(a+b)(a−b)

=(a−2a−3b)(a+2a+3b)

=(−a−3b)(3a+3b)

=−3(a+3b)(a+b)

Answer 2

Answer:

2( -2 + 3x) -6+6x

-4+6x -6 +6x

-10+12x

12x = 10

x = 10/12

= 5/6
