Write 2x2 – 16x + 14 = 0 in the form (x - p)2 = q by completing the square.
Fed [463]

completing the square we get: (x-4)^2=23

Step-by-step explanation:

We need to write 2x^2-16x+14=0 in the form (x-p)^2 =q by completing the square.

For completing the square, the formula used is: (a+b)^2=a^2+2ab+b^2

2x^2-16x+14=0

Taking 2 common:

2(x^2-8x+7)=0

Divide both sides by 2

x^2-8x+7=0

Now making complete square:

We know a but we need to find b for completing the square formula.

Since the middle term of formula is 8x which is obtained by 2(a)(b) where 2(x)(4) so, b=4 and b^2=(4)^2

So, if we add and subtract (4)^2 then we can make it complete square

(x)^2-2(x)(4)+(4)^2-7-(4)^2

(x-4)^2-7-16=0\\(x-4)^2-23=0\\(x-4)^2=23

So, completing the square we get: (x-4)^2=23

Given the line below.
Roman55 [17]

Answer:

The equation of the line in point slope form is equal to

y+2=(x+2)

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

(-2,-2) and (2,2)

substitute the values

m=\frac{2+2}{2+2}=1

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=1\\(x1,y1)=(-2,-2)

substitute the values in the formula

y-(-2)=(1)(x-(-2))\\y+2=(x+2)
