The complete square of the given polynomial is

(x+\frac{3}{2})^2=\frac{43}{12}

<h3>What is the completing the square method?</h3>

For solving the quadratic equation by completing the square, we first need to ensure that the constant of the square variable is unit.

Following are the steps involved

5x^2+15x-4=0

divide both side by 5

x^2+3x-\frac{4}{3}=0

add 9 on both sides of the equations

x^2+3x-\frac{4}{3}-9/4+ 9/4=0

x^2+3x+ 9/4=\frac{4}{3}+9/4\\(x+3/2)^2=43/12

Therefore we the complete square of the given polynomial is

(x+\frac{3}{2})^2=\frac{43}{12}

Given: f(1) = 3x– 7, 9(x) = 2x^2 – 3x +1, h(x) = 4x + 1, k(x) = –x^2+3<br> Find: (h o g) (x)
grin007 [14]

Answer:

(h o g) (x) = h(g(x))

Step-by-step explanation:

(h o g) (x) = h(g(x)) = 4(g(x))+1 = 4(2x^2 -3x + 1 ) + 1

= 4*2x^2 - 4*3x + 4*1 + 1

= 8x^2 - 12x + 4 + 1

= 8x^2 - 12x + 5
