Ifα and β are zeroes ofpolynomíal 6x2-7x-3, then form a quadratic polynom twhere zeroes are 2α and 2β |
|
Answer» When a and b are zeroes of 6x² - 7x - 3 a + b = 7/6 ab = -3/6 = -1/2 So, Any equation having 2a and 2b as roots can be written as (x - 2a) ( x - 2b) = 0 = x² - 2( a + b)x + 4ab = 0 = x² - 2 × 7/6 x + 4 × (-1/2) = 0 = x² -7/3 x - 2 = 0 multiply by 3 3x² - 7x - 6 = 0 |

The angles of triangle are (5y15)0. (6y- 15)0 and 9y0 Find the valuc of y and each angle?5)o and 9y Find the value of y and each angle? |
|
Answer» We know,Sum of all angles of triangle is 180° Then,(5y - 15) + (6y - 15) + 9y = 180 20y - 30 = 180 20y = 210 y = 210/20 = 10.5 Therefore, value of y = 10.5Angles are:(5y - 15) = 5*10.5 - 15 = 37.5°(6y - 15) = 6*10.5 - 15 = 48°9y = 9*10.5 = 94.5° |
