Answer:

see explanation

Step-by-step explanation:

Given

- \frac{1}{2} [ - \frac{3}{2} c + 6c + 1 ] - 3c

Distribute the square bracket by - \frac{1}{2}

= \frac{3}{4} c - 3c - \frac{1}{2} - 3c ← combine like terms

= \frac{3}{4} c - 6c - \frac{1}{2}

= \frac{3}{4} c - \frac{24}{4} c - \frac{1}{2}

= - \frac{21}{4} c - \frac{1}{2}

Follow the process of completing the square to solve x^2 - 10x + 8 = 0. What is the value of the constant that will be isolated
My name is Ann [436]
To solve using completing square method we proceed as follows:
x^2-10x+8=0
x^2-10x=-8
but
c=(b/2)^2
c=(10/2)^2=25
thus we can add this in our expression to get
x^2-10x+25=8+25
factorizing the LHS we get:
(x-5)(x-5)=33
(x-5)^2=33
getting the square roots of both sides we have:
x-5=+/-√33
x=5+/-√33

Answer:

x = -3

Step-by-step explanation:

(x - 2)^3 + 13 = -112

Subtract 13 from both sides

(x - 2)^3  = -125

Take the cube root of both sides

x - 2 = -5

Add 2 to both sides

x = -3
