PLEASE HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

$- 10(2) + y = 4$

$- 20 + y = 4$

$y = 24$

$- 10( 1) + y = 4$

$- 10 + y = 4$

$y = 14$

$- 10(0) + y = 4$

$0 + y = 4$

$y = 4$

$- 10( - 1) + y = 4$

$10 + y = 4$

$y = - 6$

$- 10( - 2) + y = 4$

$20 + y = 4$

$y = - 16$

In this problem, we need to plug in the given x values for $f(x)=0$ and find a and b.

When we plug in 1, we get: $2 \times {1}^{4} - 5 \times {1}^{3} - 14 \times {1}^{2} + a \times 1 + b = 0$

Simplify:
$2 - 5 - 14 + a + b = 0$
$- 17 + a + b = 0$
$a + b = 17$

We got our first statement about the values of the variables. If we find one more we can find those 2 variables.

We have another given root: 4.

Plug it in:
$2 \times {4}^{4} - 5 \times {4}^{3} - 14 \times {4}^{2} + a \times 4 + b = 0$
$512 - 320 - 224 + 4a + b = 0$
$- 32 + 4a + b = 0$
$4a + b = 32$

Now we have our second one. We can combine them:
$a + b = 17 \\ 4a + b = 32$

I use elimination method which is easier here.

Multiply the top equation by -1: $- a - b = - 17 \\ 4a + b = 32$

Add them up:
$3a = 15$

Simplify:
$a = 5$

Now we have a, we can plug in one of those equations to find b:
$5 + b = 17$
$b = 17 - 5$
$b = 12$

So, the answers are $a=5$ and $b=12$ .

Answer:

Step-by-step explanation:

since it's a multiplication consider the two factors one by one

cubic root of y^6 = y^(6/3) = y^2

cubic root of 8x^3= 2x^(3/3)= 2x

so 2xy^2
