4x² + 2x - 30 = 0
<span>
factor out the GCF:
</span>2(2x² + x - 15) = 0
<span>
factor the trinomial completely:
2x</span>² + x - 15 = 0
2x² + 6x - 5x - 15 = 0
2x(x + 3) - 5(x + 3) = 0
(2x - 5)(x + 3) = 0
<span>use the zero product property and set each factor equal to zero and solve:
2x - 5 = 0 or x + 3 = 0
2x = 5 x = -3
x = 2.5
</span><span>The roots of the function are x=-3, x=2.5</span>
Answer:
Which do you need help with?
1. -6 is 4 units from -2 in the negative direction.
2. A. and D
Step-by-step explanation:
When adding negative numbers the negative will be more, but if you are adding positive and negative numbers, whichever sign (+ or -) has the bigger number then that is the sign of the answer.
Additive inverses are when two numbers are added together to equal zero. Therefore if you have -3+3, it would be an additive inverse.
Hope this helps.
Approximately 3.47 meters is equal to 11.4 feet
Your product is 900 and you used associative property
When you have the same denominator. Other than that have different denominators will not be possible.
