To factor the trinomial, you can use the ac method where you multiply the first and last terms together (6 and 9) and add up to 15.
In this case ac= 54
2 numbers that multiply to 54 and add up to 15 would be 6 and 9 so place these numbers where the 15 would be:
Then group terms to simplify:
Simplify any like terms:
And group together again:
You can simplify a 3 out of the first expression one more time to get:
Which would be the factored form. I hope this helps :)
Answer:
x = 5
Step-by-step explanation:
given
4x - 2 = - 7 + 5x
collect terms in x on one side of the equation and numeric values on the other side.
Subtract 4x from both sides
- 2 = - 7 + x ( add 7 to both sides )
5 = x ⇒ x = 5
B
the equation representing proportional relationship is
y = mx
the equation must pass through the origin which y = mx does
For this case we must find the roots of the following equation:
We have to:
Where:
Substituting the values:
We have two roots:
