4(x2)=3(1.5x)

Solution for 4(x2)=3(1.5x) equation:

4(x2)=3(1.5x)

We move all terms to the left:

4(x2)-(3(1.5x))=0

We add all the numbers together, and all the variables

4x2-(3(+1.5x))=0

We add all the numbers together, and all the variables

4x^2-(3(+1.5x))=0


We calculate terms in parentheses: -(3(+1.5x)), so:

3(+1.5x)

We multiply parentheses

3x

Back to the equation:

-(3x)


a = 4; b = -3; c = 0;
Δ = b2-4ac
Δ = -32-4·4·0
Δ = 9
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{9}=3$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-3)-3}{2*4}=\frac{0}{8}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-3)+3}{2*4}=\frac{6}{8}
=3/4
