Answer:

3x^2 -(6-5)x-10=0

3x^2 -6x+5x-10=0

3x(x-2)+5(x-2)=0

(x-2) (3x+5) = 0

either,

x -2 =0

x=2

then,

3x +5=0

x= -5/3

3. Show that the expression 3b - 4 + 6(b-9) is equivalent to the expression 9 (b-6) -4. Show your work. ANSWER ASAP PLZZ
sattari [20]

EDITED:

so lets make the question more clear

lets make it like this, if were gonna make 10 = b vv (sorry I meant to say 10, but I said 6 ;-;

3(10) - 4 + 6(10-9) = 30 - 4 + 6 = 26 + 6 = 32

= THIS EQUALS 32

Now lets do 9(b-6) - 4 which will be turned into 9(10-6) - 4 = 36 - 4                          = THIS EQUALS 32

MY ANSWER IS YES (DONT ASK ME WHY IM WRITING IN CAPS (((: )
