What are the solutions to 6x^2-5x-4=0?

x=−1/2,4/3

Step-by-step explanation:

1. Split the second term in 6x^2−5x−4 into two terms.

6x^2+3x−8x−4=0

2. Factor out common terms in the first two terms, then in the last two terms.

3x(2x+1)−4(2x+1)=0

3. Factor out the common term 2x+1.

(2x+1)(3x−4)=0

4. Solve for x.

Ask: When will (2x+1)(3x−4) equal zero?

When 2x+1=0 or 3x-4=0

Solve each of the 2 equations above.

x=−1/2,4/3

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

answer: x=3 and y=4
