Answer:
Step-by-step explanation:
factor each term into powers of primes
75 = 3×5²
20 = 2²×5
Greatest common factor = 5
75+20 = 5(15+4)

Answer:
y = -(x + 1)² + 4
Step-by-step explanation:
y = -x² − 2x + 3
First, factor the leading coefficient from the first two terms.
y = -(x² + 2x) + 3
Complete the square.
y = -(x² + 2x + 1 − 1) + 3
Simplify and factor.
y = -(x² + 2x + 1) + 1 + 3
y = -(x + 1)² + 4
<span>The quotient is 6 and remainder is 6, because 8 goes into 52 6 times and that equals 48. Since 52-48=4, the remainder is 4.</span>
