Question

solve by completing the square t2+3t=7

Answer 1

Answer: t = Minus 3/2 plus the whole square root of 37/4. And,

              t = Minus 3/2 minus the whole square root of 37/4.

Step-by-step explanation: t^2+3t=7

t^2+3t+9/4=7+9/4

[t+3/2]^2=37/4

t+3/2=+or-37/4 {square root both sides}

Which gives,

t = Minus 3/2 plus the whole square root of 37/4. And,

t = Minus 3/2 minus the whole square root of 37/4.
