Answer:

See below

Step-by-step explanation:

(ii) \\  \\  {x}^{3}  + 2 {x}^{2}  + 5x + 10 \\  \\  =  {x}^{2} (x + 2) + 5(x + 2) \\  \\  = (x + 2)( {x}^{2}  + 5) \\  \\ (iii) \\  {a}^{3}  -  {a}^{2}  {b}^{2}  - ab +  {b}^{3}  \\  \\  =  {a}^{2} (a -  {b}^{2} ) - b(a -  {b}^{2} ) \\  \\  = (a -  {b}^{2} )( {a}^{2}  - b)

Write the quadratic equation y= x^2 -6x = 7 in vertex form.
lapo4ka [179]

Answer:

(x - 3)² - 16 = 0

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Subtract 7 from both sides

x² - 6x + 7 = 0 ← in standard form

with a = 1, b = - 6

Given a quadratic in standard form then the x- coordinate of the vertex is

x_{vertex} = - \frac{b}{2a} = - \frac{-6}{2} = 3

Substitute x = 3 into the equation for y

y = 3² - 6(3) - 7 = 9 - 18 - 7 = - 16 ⇒ (h, k) = (3, - 16)

y = (x - 3)² - 16 = 0
