Simplify the given expression below: (6 + 21) – (8 - 31)
0-2 + 51
0-2 - 1
O 8 + 51
O 8 - 5

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

n=1.75+1.75

step-by-step explanation:

3.5/2=1.75
