Use the solutions below to write the quadratic expression in standard form. x = 3/4 and x = -5/6

Answers

Answer:

Hi,

Step-by-step explanation:

The sum of the roots is:

$(3)/(4) -(5)/(6) =-(1)/(12) \n$

The product of the roots is:

$(3)/(4) *(-(5)/(6)) =-(5)/(8) \n$

Quadratic equation in standard form is:

$x^2+(x)/(12) -(5)/(8) =0\n$

Choose the correct simplification of the expression (4a^4b)^2.

Answers

Answer:

The simplified expression is $16a^(8b)$

Step-by-step explanation:

we need to simplify the expression $(4a^(4b))^(2)$

$(4a^(4b) )^(2)$

Using exponent rule : $(a* b)^(n) = a^(n)b^(n)$

$4^(2)(a ^(4b))^(2)$

$16(a ^(4b) )^2$

Apply exponent rule :

$(a^b)^c= a ^(b*c)$

$(a ^(4b) )^2= a ^(8b)$

$16a^(8b)$

Hence, simplified expression is $16a^(8b)$

$(4a^(4b) )^(2)$

Apply exponent rule : $(a*b)^n = a^nb^n$

$4^2(a ^(4b))^2$

$(a ^(4b) )^2$

Apply exponent rule :

$(a^b)^c= a ^(b*c)$

$= a ^(8b)$

$= 4^2 = 16$

$=\ \textgreater \ 16 a ^(8b)$

hope this helps!

What is y= -x^2-2x+3 in vertex form

Answers

y = -x² - 2x + 3
  y - 3 = -x² - 2x + 3 - 3
  y - 3 = -x² - 2x
y - 3 - 1 = -x² - 2x - 1
  y - 4 = -(x²) - (2x) - (1)
  y - 4 = -(x² + 2x + 1)
  y - 4 = -(x² + x + x + 1)
  y - 4 = -(x(x) + x(1) + 1(x) + 1(1))
  y - 4 = -(x(x + 1) + 1(x + 1))
  y - 4 = -(x + 1)(x + 1)
  y - 4 = -(x + 1)²
y - 4 + 4 = -(x + 1)² + 4
y = -(x + 1)² + 4

Step-by-step explanation:

Step 1: Define

Identify

f(x) = 4x - 6

g(x) = 6x - 4

Step 2: Find f · g

Substitute in function values: f · g = (4x - 6)(6x - 4)
Expand [FOIL]: f · g = 24x² - 16x - 36x + 24
[Subtraction] Combine like terms: f · g = 24x² - 52x + 24
