A. 3x² - 19x + 15
-
B. None of these
-
C. 3x² - 19x - 15
-
D. 3x² + 19x - 15
Explanation
First polynomial: 8x² + 10x - 25
Second polynomial: 5x² - 9x - 10
(8x² + 10x - 25) - (5x² - 9x - 10)
= 8x² + 10x - 25 - 5x² + 9x + 10
= 3x² + 19x - 15
Explanation
4 + 4 - (4 x 4) + 4 =
4 + 4 - 16 + 4 =
4 + 4 - 16 + 4 =
12 -16 = -4
ANS = -4
Explanation
- Let's solve the expression:
- (6 x 11) - (28 + 38) = (66) - (66) = 0
- So, the answer is 0.
