0 = (1x+1) (1x-3) if m (x) = 10, find the value of x

x=1+sqrt (14) & 1-sqrt (14).

Step-by-step explanation:

(1x+1) (1x-3) = 0

(x+1) (x-3) = 0

m (x) = (x+1) (x-3) = 10

(x+1) (x-3) = 10

x^2+x-3x-3=10

x^2-2x-3=10

x^2-2x-3-10=0

x^2-2x-13=0

Apply the quadratic formula with a=1, b=-2 and c=-13.

The answer is x=1+sqrt (14) & 1-sqrt (14).
