Find polynomial whose zeros are 3 and -4​

Mathematics
1 answer:
horrorfan [7]3 years ago
6 0

Answer:

Simplest polynomial: x²+x-12

Step-by-step explanation:

zeroes of polynomial= 3,-4

Therefore,

f(3) =0

f(-4)=0.

By factor Theorem

(x-3) and (x+4) are factors

so simplest polynomial is

(x-3)(x+4)

= x² - 3x + 4x -12

= x² + x -12

.

Hope it helps

Write the equation of the line that goes through each set of points (-1,6),(3-2)
Mariana [72]

The point-slope form:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-1, 6) and (3, -2). Substitute:

m=\dfrac{-2-6}{3-(-1)}=\dfrac{-8}{4}=-2\\\\y-6=-2(x-(-1))\\\\y-6=-2(x+1)\qquad\text{use distributive property}\\\\y-6=-2x-2\qquad\text{add 6 to both sides}\\\\y=-2x+4\qquad\text{add 2x to both sides}\\\\2x+y=4

<h3>Answer:</h3><h3>y - 6 = -2(x + 1)    <em>point-slope form</em></h3><h3>y = -2x + 4      <em>slope-intercept form</em></h3><h3>2x + y = 4     <em>standard form</em></h3>
