-- Find how much 'y' changes from the first point to the second one.

-- Find how much 'x' changes from the first point to the second one.

-- The slope of the line going from the first point to the second one is

(change in 'y') / (change in 'x') .

(2a+b)^2 how do you do this

gulaghasi [49]

• Expand (2a + b)²:

(2a + b)²

= (2a + b) · (2a + b)

Multiply out the brackets by applying the distributive property of multiplication:

= (2a + b) · 2a + (2a + b) · b

= 2a · 2a + b · 2a + 2a · b + b · b

= 2²a² + 2ab + 2ab + b²

Now, group like terms together, and you get

= 2²a² + 4ab + b²

= 4a² + 4ab + b² <——— expanded form (this is the answer).

I hope this helps. =)

Use basic identities to simplify the expression.<br> cos θ - cos θ sin2θ

Fynjy0 [20]

Cos Ф - cos Ф.sin² Ф

sin² Ф = 1 - cos² Ф
cos Ф - cos Ф( 1-cos² Ф) = cos Ф - cos Ф - cos³ Ф = cos³ Ф

cos Ф - cos Ф.sin² Ф = cos³ Ф

Oksanka [162]

Answer:

x = 2, and 6

x = 2 , 6

Step-by-step explanation:

The quadratic function to analyze is: $y = -x^2+8x-12$

In order to find where the corresponding parabola intercepts the x axis, we set it equal to zero (y = 0):

$y = -x^2+8x-12\\0 = -x^2+8x-12\\x^2-8x+12=0$

This equation is easy to solve by factoring. We look for a air of integer numbers whose product equals the constant term "12", and whose combinig renders the coefficient of the middle term of the trinomial "-8".

The two such numbers are "-2" and "-6". We use them to split the middle term, and then solve by factoring by grouping:

$x^2-8x+12=0\\x^2-2x-6x+12=0\\(x^2-2x)+(-6x+12)=0\\x(x-2)-6(x-2)=0\\(x-2)(x-6)=0$

For the product of two factors to render zero, we need either one to be a zero.This means that (x-2)=0 (that is x = 2), or (x-6)=0 (that is x = 6).

So, there are two x-intercepts: x= 2, and 6
