Solve the quadratic equation by the square root property. (2x + 5)2 = 49

x=1  and x=-6

Step-by-step explanation:

(2x + 5)^2 = 49

Take the square root of each side

sqrt((2x + 5)^2) = ±sqrt(49)

2x+5 = ±7

Subtract 5 from each side

2x+5-5 = 7-5        2x+5-5 = -7-5

2x = 2                   2x  =-12

Divide by 2

2x/2 =2/2                 2x/2  = -12/2

x =1                            x = -6

answer: no
