a = -3 and b = 1
Step-by-step explanation:
x² - 6x + 10
→ Half the second term and place it in the bracket
( x - 3 )²
→ Square -3
- ( 3 )² = -9
→ Place this outside the brackets along with plus 10
( x - 3 ) ² - 9 + 10
→ Simplify
( x - 3 ) ² + 1

Answer:
5/7
Step-by-step explanation:
first of mean to divide
so it really saying x ÷ 3/4 and x = 15/28
15/28 ÷ 3/4 but you cant divide fractions
so we use copy dote flip
copy 15/28
dote ×
flip 4/3
15/28 × 4/3
then cross simplafiy so 4 can go into 28, 7 rimes. and 3 can go into 15, 5 times
5/7
