Hello:-
this(*)is counted as multiplication
1. 4*2 + (-2+8)
=8+(6)
=14
2. (-2)*2 + 4
= -4+4
=0
3. 8*4/-2
= -32/2 (as -ve sign cannot be in denominator)
= -16
4. -2*4/8
= -8/8
= -1
5. -2*8/4
= -16/4
= -4
therefore it is a. -4
I hope it will help u !!!!!!!!!
Answer:
x = -3 and x = -3/2
Step-by-step explanation:
After writing down the polynomial, split it; put a line between 3x^2 and -18x. Look and 2x^3 + 3x^2 and -18x - 27 separately and factor them both:
p(x) = 2x^3 + 3x^2 <u>- 18x -27</u>
p(x) = x^2(2x+3) <u>-9(2x+3)</u>
Now notice how x^2 and -9 have the same factor (2x+3). That means x^2 and -9 can go together:
p(x) = (x^2 - 9)(2x+3)
Factor it once more because there's a difference of squares:
p(x) = (x+3)(x-3)(2x+3)
Now just plug in whatever makes the each bracket equal 0:
x = -3, x = 3, and x = -3/2
Those are your zeros.
