the function h(x) is quadratic and h(3) = h(–10) = 0. which could represent h(x)? h(x) = x2 – 13x – 30 h(x) = x2 – 7x – 30 h(x)

= 2x2 26x – 60 h(x) = 2x2 14x – 60

Answer:

h(x) = 2x^2+14x - 60

Step-by-step explanation:

h(3) = h(–10) = 0

h(3) means x=3

h(-10) means x=-10

Plug in x values and find out h(3) and h(-10)

LEts check with each option

h(x) = x^2 - 13x - 30

h(3) = 3^2 - 13(3) - 30=-60 h(3) is not equal to 0

LEts check with option B

h(x) = x^2 - 7x - 30

h(3) = 3^2 - 7(3) - 30=0  h(3) is not equal to 0

option C

h(x) = 2x^2 +26x - 60

h(3) = 2(3)^2+26(3)-60=36  h(3) is not equal to 0

option D

h(x) = 2x^2+14x - 60

h(3) = 2(3)^2+14(3)-60=0  h(3) is equal to 0

Plug in -10 for x

h(3) = 2(-10)^2+14(-10)-60=0  h(-10) is equal to 0

h(3)=h(-10)=0\\\\therefore\\\\h(x)=a(x-x_1)(x-x_2)\\\\h(x)=a(x-3)(x+10)=a(x^2+7x-30)\\\\Answer:\boxed{h(x)=x^2+7x-30}

Which statement is true about polynomial 5s^6t^2 + 6st^9 - 8s^6t^2 - 6t^7 after it has been fully simplified?
Marina86 [1]

Answer:  3t²(2st⁷ - s⁶ - 2t⁵)

<u>Step-by-step explanation:</u>

5s⁶t² + 6st⁹ - 8s⁶t² - 6t⁷     <em>5s⁶t² and - 8s⁶t² are like terms which = -3s⁶t² when combined</em>

=          6st⁹ - 3s⁶t² - 6t⁷      <em>next, factor out the GCF of 3t²</em>

=      3t²(2st⁷ - s⁶ - 2t⁵)
