Answer:
Step-by-step explanation:
<em>(a).</em> 2( 2 )³ + a ( 2 )² - b ( 2 ) + 12 + ( 18 ) = 0
16 + 4a - 2b + 30 = 0
4a - 2b = - 46
<em>2a - b = - 23</em> ....... <em>( 1 )</em>
2 ( - 4 )³ + a ( - 4 )² - b ( - 4 ) + 12 = 0
- 128 + 16a + 4b + 12 = 0
16a + 4b = 116
<em>4a + b = 29</em> ........ <em>( 2 )</em>
<em>( 1 )</em> + <em>( 2 )</em>
6a = 6 , <em>a = 1</em>
4(1) + b = 29 , <em>b = 25</em>
<em>(b).</em> 2x³ + x² + 25x + 12 = 0
= <em>- 4</em> ( given: f(x) is divisible by x + 4 )
= <em>0.5</em>
= <em>3</em>
Answer:
27x^6 y^9
z^9
Step-by-step explanation:
That should be the answer,if not...sorry!:)
p(x) × q(x)
= (3x² - x + 1) × (2x² + 3x - 2)
= 6x⁴ + 9x³ - 6x² - 2x³ - 3x² + 2x + 2x² + 3x - 2
= 6x⁴ + 7x³ - 7x² + 5x - 2
