If - 1 is a zero then
is a factor.
Dividing with this factor using the long division approach, we get the quadratic factor to be,
(see attachment).
We can rewrite the polynomial as
We can further factor as
That is
First you would simplify the equation <span>(7x²+2x+5)+(3x²-8x-10) lets start with the first part
</span><span>(7x²+2x+5)
</span>7x² + 2x which = 49x + 2x which also = 51x Then you add the last part (+5)
51x + 5
Now you simplify the last part.
<span>(3x²-8x-10)
</span>3x²-8x which=9x - 8x which also = 1x or simply x Then add the last part (-10) Which you'll get x-10
51x + 5) + (x - 10) = 52x -5
so your answer is 52x - 5

<h3>
Step-by-step explanation:</h3>
When you square the binomial (a -b), you get ...
... (a -b)² = a² -2ab +b²
That is, both the a² and b² terms have positive signs, and the middle term is twice the product of the roots of the squared terms.
The last two selections have negative signs on the constant, so cannot be perfect square trinomials.
The first selection has a middle term that is -ab, not -2ab, so it is not a perfect square trinomial, either.
The second selection is the correct one:
... 4a² -20a +25 = (2a +5)²
Answer:
a(
+
) = = -13
Step-by-step explanation:
Given that a = -1, b=2 and c= -3
find the value of a(+)
Just substitute the values given for each variable
a(+) = (-1)(
+
) ; do the exponents first
a(+) = (-1)(4+9)=(-1)(13) ; now add inside the parenthesis;
a(+) = -13 ; and multiply by -1
