6.XY

What about the last two terms? Observe the

Il you change their order to - 9x+6, the fa

(3x - 2) will come out

9x+6= - 3 (3x) + 3 (2)

- 3 (312)

Step 3. Putting (a) and (b) together,

Answer 2

Answer:

x=7

Step-by-step explanation:

=√(x*48x + 14*48x) = 56+4x

48x^2 + 672x = (56 + 4x)^2

48x^2 + 672x = 3136 + 16x^2 + 448x

32x^2 + 224x = 3136

32x^2 + 224x - 3136 = 0

taking 32 as common we have

x^2 + 7x -98 =0

splitting the middle term

x^2 + 14x -7x -98= 0

x(x+14) -7(x+14)

(x-7) (x+13)=0

x= 7; -13

x=7
