Jackson used the process of completing the square to solve the equation 2x2−12x=−6.

Nikolay [14]

Answer:

$x=3-\sqrt{6},x=3+\sqrt{6}$

Step-by-step explanation:

we are given equation as

$2x^2-12x=-6$

Since, we have to solve it by using complete square

so, firstly we will complete square

and then we can solve for x

step-1:

Factor 2 from both sides

$2(x^2-6x)=-3\times 2$

step-2:

Simplify it

$x^2-6x=-3$

step-3:

Add both sides 3^2

$x^2-6x+3^2=-3+3^2$

now, we can complete square

$(x-3)^2=6$

step-4:

Take sqrt both sides

$(x-3)=-\sqrt{6},(x-3)=\sqrt{6}$

step-5:

Add both sides by 3

we get

$x=3-\sqrt{6},x=3+\sqrt{6}$

Find two consecutive even integers such that twice the smaller is 16 more than the larger.

qwelly [4]

Answer: smaller: 18 ; larger: 20

kakasveta [241]

1.3 x 0.4 x 2 = 1.04
0.5 x 0.4 = 0.2
( $\frac{1}{2}$ (0.5 x 1.2)) x 2 = 0.6

1.04 + 0.2 + 0.6 = 1.84m²
