What are the x-intercepts of y=2x^2+6x-20?
NISA [10]

Answer:

the x-intercepts are -5 and 2

Step-by-step explanation:

y=2x^2+6x-20

x-intercept is when y is set equal to zero

So, y = 0

0 = 2x^2+6x-20

2x^3+6x-20 = 0\\Taking \ 2 \ common\\2(x^2+3x-10) = 0\\Dividing \ both \ sides \ by \ 2\\x^2+3x-10 = 0\\Using \ mid\ term \ break \ formula\\x^2+5x-2x-10 = 0\\x(x+5)-2(x+5)=0\\Taking \ (x+5) \ common\\(x+5)(x-2) = 0

Either,

x+5 = 0    <u><em> OR </em></u>    x-2 = 0

x = -5       <u><em> OR  </em></u>     x = 2

So, the x-intercepts are -5 and 2

E5 In (x + 1)<br> Simplify
pentagon [3]

Answer:

e^ (5 ln (x + 1))   = (x + 1)^5

Step-by-step explanation:

e5 In (x + 1)  or did you mean   e^ (5 ln (x + 1))

because then this would simplify a lot

e^ (5 ln (x + 1))  = e ^ (ln (x + 1)^5)

e^ (5 ln (x + 1))  = e ^ (ln (x + 1)^5) = (x + 1)^5

or did you mean  (e^5) ( ln (x + 1))  =  ln [(x+1)^(e^5)]

But I think you meant:

e^ (5 ln (x + 1))  = e ^ (ln (x + 1)^5) = (x + 1)^5
