Answer:
a = p * q
b = p * s + q * r
c = r * s
Step-by-step explanation:
In the trinomial ax² + bx + c
a is the coefficient of x²
b is the coefficient of x
c is the numerical term
∵ The trinomial is ax² + bx + c
∵ Its factors are (px + r) and (qx + s)
∴ ax² + bx + c = (px + r)(qx + s)
∵ (px + r)(qx + s) = (px)(qx) + (px)(s) + r(qx) + (r)(s)
∴ (px + r)(qx + s) = pqx² + (psx + qrx) + rs
∴ ax² + bx + c = pqx² + (ps + qr)x + rs
→ By comparing the two sides
∵ ax² = pqx² ⇒ divide both sides by x²
∴ a = pq
∵ bx = (ps + qr)x ⇒ Divide both sides by x
∴ b = ps + qr
∴ c = rs
∴ a = p * q
∴ b = p * s + q * r
∴ c = r * s
least common multiple of the given three numbers can be found out as follows
first have to divide all three numbers by factors that are common for all three
so first divide 55, 75 and 115 by 5
55/5 = 11
75/5 = 15
115/5 = 23
there are no common factors shared by 11, 15 and 23
so the factors are 5, 11 , 15 and 23
so to find the least common multiple
we have to find the products of the factors
5 x 11 x 15 x 23 = 18 975
least common multiple is 18 975
