Factor the polynomial 16b^4+30b^3-12b^2
Lelu [443]

Answer:

2b²(8b²+15b-6)

Step-by-step explanation:

16b^{4}+30b³-12b²

2b²(8b²+15b-6)

This is not further factorable. If you want to find the roots, you'd have to use the quadratic formula for the polynomial in the parentheses. Therefore that is our final answer.

<u>Given</u><u> </u><u>:</u><u>-</u>

  • The roots of the function are 5 and -3 .

<u>To</u><u> </u><u>Find</u><u> </u><u>:</u><u>-</u>

  • The Quadratic function .

<u>Answer</u><u> </u><u>:</u><u>-</u>

The roots of the function are 5 and -3 . In general we can write the Quadratic function with roots π and ∆ as ,

\sf\longrightarrow f(x) = ( x - π )(x-∆)

So on using this we have ,

\sf\longrightarrow f(x) = ( x -5)( x -(-3))

\sf\longrightarrow f(x) = (x-5)(x+3)

\sf\longrightarrow f(x) = x(x-5)+3(x-5)

\sf\longrightarrow f(x) = x² -5x +3x -15

\sf\longrightarrow f(x) = x² -2x -15

<u>Hence </u><u>the</u><u> required</u><u> </u><u>answer</u><u> </u><u>is </u><u>x²</u><u> </u><u>-2x </u><u>-</u><u>1</u><u>5</u><u>.</u>
