Question

 

slove

 

6x²+7x=20

Answer 1

Jessica,

 

Are you familiar with the quadratic formula?

 

For

 

ax² + bx + c = 0,

 

x = [-b ± √(b² - 4ac)] / 2a

 

In this problem,

 

6x² + 7x = 20

6x² + 7x - 20 = 0

a = 6

b = 7

c = -20

 

Substitute these values into the quadratic formula to find two possible values for x.

 

Answer 2

6x² + 7x = 20

6x² + 7x - 20 = 0

6x² - 15x + 8x - 20 = 0

3x(2x - 5) + 4(2x - 5) = 0

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

 

Can you solve for x?
