4. Solve the quadratic by completing the square. 4x² + 16x +49 = 8

Setler79 [48]

values of x are $x=\frac{5i}{2}-2\,\,and\,\,x=\frac{-5i}{2}-2$

Step-by-step explanation:

We need to solve the equation $4x^2+16x +49 = 8$ by completing square.

Solving:

$4x^2+16x +49 = 8\\4x² + 16x +49-8 = 0\\4x² + 16x +41 = 0\\$

We need to make the completing square form: $(a)^2+2(a)(b)+(b)^2=(a+b)^2$

$4x^2 + 16x +41 = 0\\Adding\,\,and\,\,subtracting\,\, 16 \\(2x)^2+2(2x)(4)+(4)^2+41-16=0\\(2x+4)^2+25=0\\(2x+4)^2=-25$

Finding value of x:

$(2x+4)^2=-25\\Taking\,\,square\,\,root\,\,on\,\,both\,\,sides:\\\sqrt{(2x+4)^2}=\sqrt{-25}\\ 2x+4=\pm5i\\so, 2x+4=5i\,\,and\,\,2x+4=-5i\\2x=5i-4\,\,and\,\,2x=-5i-4\\x=\frac{5i-4}{2} \,\,and\,\,x=\frac{-5i-4}{2} \\x=\frac{5i}{2}-2\,\,and\,\,x=\frac{-5i}{2}-2$

So, values of x are $x=\frac{5i}{2}-2\,\,and\,\,x=\frac{-5i}{2}-2$

If the sum of two numbers is 15 and their quotient is 4, what are they?

11Alexandr11 [23.1K]

Answer:

3, 12

Step-by-step explanation:

"x" is the larger number,

"y" is the smaller number.

Given

x + y = 15

x / y = 4

manipulate the equations for the problem

x / y = 4

*y *y

x = 4y

solve the system of equations by the methord of substitution:

x + y =15

4y + y = 15

5y = 15

y = 3

Subsitute back into the equations given.

x = 4y

x = 12
