Question

minus 4 x square - 7 x + 12 is equal to zero use the quadratic formula ​

Answer 1

Explanation:

-4x²-7x+12=0

ax²+bx+c=0

a= -4 , b= -7 , c= 12

Using Quadratic Formula,

x= - b + √b²-4ac/2a and x= - b - √b²-4ac/2a

Therefore,

x= -(-7) + √(-7)²-4(-4)(12)/2(-4) and x= -(-7) - √(-7)²-4(-4)(12)/2(-4)

Now,

x= 7 + √49 + 192/-8 and x= 7 - √49 + 192/-8

x= 7+ √241 /-8 and x= 7 - √241 /-8

Hope it helps you
