Answer:
t=-1, t=-9
Step-by-step explanation:
✓Convert the given to standard form before solving.
✓Always divided by 2
✓Always square the quotient
✓The sign beside b is always (+)
= t²+10t= --9.
find a value that is equal to the square of half of b
=(b/2)² = 5²
= t² + 10t +(5)² = --9+(5)²
= t²+10t+25=16
= (t+5)²=16
= t+5=±√16
= t+5 = 4
= t= 4--5
t= --1
= t +5 = 4
= t = --4--5
t = --9
t = --1,--9
