Quadratic formula since this trinomial is not factorable.
$\frac{ - b + - \sqrt{ {b}^{2} - 4ac } }{2a} \\ \frac{ - 1 + - \sqrt{ {(1)}^{2} - 4(1)( - 1) } }{2(1)} \\ \frac{ - 1 + - \sqrt{1 + 5} }{2} \\ \frac{ - 1 + - \sqrt{6} }{2} \\ x = \frac{ - 1 + \sqrt{6} }{2} \\ x = \frac{ - 1 - \sqrt{6} }{2}$

Answer:

The answer is 8.6×10¹⁴

Step-by-step explanation:

You can evaluate it :

$(4.3 \times {10}^{8} ) \times (2.0 \times {10}^{6} )$

$= (4.3 \times 2.0) \times ( {10}^{8} \times {10}^{6} )$

$= 8.6 \times {10}^{8 + 6}$

$=8.6 \times {10}^{14}$

Q # 4 Simplify the product

timama [110]

For this case we have the following product:
$(x-4) (x + 3)
$
We must use the distributive property correctly to solve the problem.
We have then:
$x ^ 2 + 3x - 4x - 12
$
Then, we must add similar terms.
We have then:
$x ^ 2 - x - 12
$
Answer:
The final product is given by:
$x ^ 2 - x - 12
$
option 2
