4x^2+7x-11=0 solve by factoring

For some reason I we didnt cover a problem like this in class and now I am super confused!!

Step-by-step explanation:

4x²+7x-11=0

4x²+(11-4)x-11=0

4x²+11x-4x-11=0

x(4x+11)-1(4x+11)=0

(4x+11)(x-1)=0

then

x=1

or

x=(-11/4)

x = 1

x = - 11/4

Step-by-step explanation:

4x² + 7x - 11 = 0

4x² - 4x + 11x - 11 = 0

4x(x - 1) + 11(x - 1) = 0

(x - 1) (4x + 11) = 0

x - 1 = 0 or 4x + 11 = 0

x = 1 or x = - 11/4
