This is all if you don't solve as a quadratic equation.
Look at the other answer.
Answer:
x = 9.75
Step-by-step explanation:
Step 1. Distribute the 2(Do 2 times 2x and 2 tiems 5)
4x + 10 = 49
Step 2. Subtract 10 from both sides.
4x = 39
Step 3. Divide it all by 4 to isolate the variable.
x = 9.75
Answer:
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
