X^2+3x=24, halve the linear coefficient, square it, and add it to both sides
In this case (3/2)^2=2.25
x^2+3x+2.25=26.25 now the left side is a perfect square...
(x+1.5)^2=26.25 take the square root of both sides
x+1.5=±√26.25 subtract 1.5 from both sides
x=-1.5±√26.25
x=-1.5-√26.25 and -1.5+√26.25
x≈ -6.62 and 3.62

.....
Answer: h(<u>5</u>)=-44
Step-by-step explanation:
Given
h(t)=-10x+6
h(?)=-44
Substitute the [-44] value to the first equation
-44=-10x+6
Subtract 6 on both sides
-44-6=-10x+6-6
-50=-10x
Divide -10 on both sides
-50/-10=-10x/-10
x=5
Hope this helps!! :)
