QUICK!! 18x^2+21x-60=0 pls give me the steps as well
Anton [14]

Answer:

<h2>x1 =  -  \frac{5}{2}</h2>

x2 =  \frac{4}{3}

Step-by-step explanation:

18 {x}^{2}  + 21x - 60 = 0

Divide both sides of the equation by 3

6 {x}^{2}  + 7x - 20 = 0

Write 7x as a difference

6 {x}^{2}  + 15x - 8x - 20 = 0

Factor out 3x from the expression

3x(2x + 5) - 8x - 20 = 0

Factor out -4 from the expression

3x(2x + 5) - 4(2x + 5) = 0

Factor out 2x + 5 from the expression

(2x + 5)(3x - 4) = 0

When the product of factors equals 0 , at least one factor is 0

2x + 5 = 0

3x - 4 = 0

Solve the equation for X

2x + 5 = 0

Move constant to R.H.S and change its sign

2x = 0 - 5

Calculate the difference

2x  =  - 5

Divide both sides of the equation by 2

\frac{2x}{2}  =  \frac{ - 5}{2}

Calculate

x 1=  -  \frac{5}{2}

Again,

3x - 4 = 0

Move constant to RHS and change its sign

3x = 0 + 4

Calculate the sum

3x = 4

divide both sides of the equation by 3

\frac{3x}{3}  =  \frac{4}{3}

Calculate

x 2=  \frac{4}{3}

Hope this helps..

Best regards!!
