What is the factorization of this polynomial -X2 - 14X - 45?
-x2-14x-45 = -(x2+14x+45) delta = 142-4*1*45=16 so x2+14x+45=(x-(-14+4)/2) (x-(-14-4)/2) = (x+5)(x+9) so -x2-14x-45 = -(x+5)(x+9)
What are the 45 times tables?
1 x 45 = 45 2 x 45 = 90 3 x 45 = 135 4 x 45 = 180 5 x 45 = 225 6 x 45 = 270 7 x 45 = 315 8 x 45 = 360 9 x 45 = 405 10 x 45 = 450 11 x 45 = 495 12 x 45 = 540
What are multiplies of 45?
The first ten positive integer multiples of 45 are as follows: 1 x 45 = 45 2 x 45 = 90 3 x 45 = 135 4 x 45 = 180 5 x 45 = 225 6 x 45 = 270 7 x 45 = 315 8 x 45 = 360 9 x 45 = 405 10 x 45 = 450
What is 4 more than 4 times x is 45?
X = 41/4
How do you solve x squared -4x equals 41?
x² - 4x = 41 → x² -4x - 41 = 0 Using the quadratic formula: x = (-b ± √(b² - 4ac))/(2a) → x = (4 ± √(4² - 4×1×-41)/(2×1) → x = (4 ± √(4(4+41)))/2 → x = (4 ± 2√45)/2 → x = 2 ± √45 → x = 2 + √45 (≈ 8.708) or x = 2 - √45 (≈ -4.708)
