Make x the subject of the formula 6x+a=5(x+t)

x = 5t - a

Step-by-step explanation:

in order to make x the subject of formulae from the expression 6x+a=5(x+t)

the first step to do is to open the bracket (BODMAS).

6x+a=5(x+t)

6x + a = 5x + 5t

collect the like terms

6x-5x = 5t - a

x = 5t - a

therefore the value of x in the expression , that is expressing x interms of t and a from the expression 6x+a=5(x+t) is solved to be x = 5t - a

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
