Solve the quadratic equation by the square root property 2x

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

A. {-6, 1}

B. {0, 1}

C. {-27, 27}

D. {1, 6}

We have

(2x+5)^2 = 49

So,we have

2x+5 = 7, 2x+5 = -7

If 2x+5 = 7

x= 1

If 2x+5 = -7

x= -6

So, roots are (-6,1)

Option A is correct

$Solve the quadratic equation by the square root property. (2x + 5) 2 = 49 A. {-6, 1} B. {0, 1} C. {-27, 27} D. {1, 6}SolutionWe have (2x+5)^2 = 49 So,we have 2x$
