Simplify the question

-4x²+5x+3

Step-by-step explanation:

Actually, the question itself is the simplified version. I just rearranged it by looking at the variable and the exponents.

Hope it helps!

Given 5x-4x²+3

so as here it is in the form of ax²+bx+c

so we have to simply make it an quadratic equation

so -4x²+5x+3 =0

so then x = -5± √5²-4(-4)×3/2(-4)

so x =√73 + 5/8 after simplification

so 5x+3 = -4x²(x-(5-√73)/8)(x-(√73+5)/8)

Hope it helps

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.

a is the correct
