Answer:
6x³ + x² - 9x +10
Step-by-step explanation:
This one uses typical FOIL multiplication.
We are given the expression (3x + 5) (2
– 3x + 2)
Using FOIL, we multiply every term in all ways. We can rewrite the expression as (3x · 2
) + (3x · -3x) + (3x · 2) + (5 · 2
) + (5 · -3x) + (5 · 2)
Which simplifies to 6x³ - 9x² + 6x + 10x²- 15x + 10
Which we can further simplify to 6x³ + x² - 9x +10
Answer:
8.333333
Step-by-step explanation:
3x+2(4+6x)=133
3x+8+12x=133 First I distibuted the 2 too the 4 and 6x
15x+8=133 Then I added the x es 3x and 12x
15x+8-8=133-8 Then I subracted 8 from both sides
15x=125 That leaves with this
15x/15=125/15 Now I divide 15 from both sides to isolate x
x= 8.33333 that is the answer
check
3x+2(4+6x)=133
3*8.333333+2(4+6*8.333333)=133
24.999999 +2(4+ 49.999998)=133
24.999999+2( 53.999998)=133
24.999999+107.999996=133
132.999995=133
