(x - x₀)² + (y - y₀)² = r²
x₀=-4; y₀=3; r=5;
(x - (-4))² + (y - 3)² = 5²
(x + 4)² + (y - 3)² = 25
Answer:
(x + 10)(2x + 5)
Step-by-step explanation:
Given
2x² + 25x + 50
Consider the factors of the product of the coefficient of the x² term and the constant term (ac) which sum to give the coefficient of the x- term (b)
ac = 2 × 50 = 100 and b = 25
The factors are + 20 and + 5
Use these factors to split the x- term
2x² + 20x + 5x + 50 ( factor the first/second and third/fourth terms )
= 2x(x + 10) + 5(x + 10) ← factor out (x + 10) from each term
= (x + 10)(2x + 5)
for a power of ten all you need is just add a zero, example, 10 to the power of 10 just add ten zeros behind the 10 -------> 100,000,000,000
