HCF × LCM = product of two numbers. 675 × 45 = 135 × x x = 675 × 45 /135 = 225. The second number is 225.

For real and equal roots, D = b^2 - 4ac = 0. (for p (x) = ax^2 + bx + c) Therefore, k^2 = 3 * 3 * 4 = 36. k = √36 = 6.//

Anmol Preet 4 years, 6 months ago

7×11×13+13 = 7×11×26 •26 is a composite number. So, 7×11×13+13 is a composite number. 7×6×5×4×3×2×1+5. In this, number 6,4 etc., are composite numbers. Also, +5 will become a composite number. 7×6×5×4×3×2×1+5 is a composite number.

Adithya Dev A 4 years, 6 months ago

The number 7 * 11 * 13 + 13 can also be written as 13 (7 * 11 + 1). This means that the number has two other factors 13 and 78 while not considering 1 and the number itself. The case is similar for the number 7 * 6 * 5 * 4 * 3 * 2 * 1 + 5 which can also be written as 5 (7 * 6 * 4 * 3 * 2 * 1 + 1). Therefore, both these numbers are COMPOSITE in nature.

Adithya Dev A 4 years, 6 months ago

a 9 = -32, a 11 + a 13 = -94. Therefore, a 9 = -32. a + 8d = -32 (1). And, a 11 + a 13 = -94. a + 10d + a + 12d = -94. 2a + 22d = -94. a + 11d = -47 (2). Solving (1) and (2), (2) - (1) ==> 3d = -15. ==> d = -5//

If alpha and beta are zeroes of polynomial f(x)= x^2-5x+4, find the value of 1/alpha +1/beta -2×alpha×beta

Posted by Anshika Pal 4 years, 6 months ago

CBSE > Class 10 > Mathematics

1 answers

Adithya Dev A 4 years, 6 months ago

f (x) = x^2 - 5x + 4 = 0. According to the relationship between zeroes and coefficients in quadratic equations, if α and β are the zeroes of f (x), then :- α + β = -b/a = 5.// αβ = c/a = 4.// Therefore, 1/α + 1/β - 2αβ = α + β/αβ - 2αβ = 5/4 - 2(4) = 5/4 - 8 = (5 - 32)/4 = -27/4 = -6.75.
