(X+3) is a factor of x³+ax²-bx+6 & a+b=7.Find the value of a&b. |
|
Answer» a=0 and b=7 First divide the given polynomial by (x+3) then you will get the remainder 6-(27-9a-3b) which you know is equal to 0 as it is given that (x-3) is a factor of the given polynomial. Then form an equation 6-(27-9a-3b)=0 which after solving you will get 3a+b=7. Then you will have two equations 3a+b=7 and a+b=7. Solve them you\'ll get ans |

Draw a line segment of length 7cm.find a point p on in which divides it in the ratio 3:5 |
| Answer» We have to draw a line segment of length 7 cm.Then,we have to find a point P on it, which divides it in the ratio 3 : 5.Steps of construction:\tDraw a line segment {tex}AB=7{/tex} cm.\tDraw a ray AX, making an acute {tex}\\angle BAX{/tex} with AB.\tMark {tex}3+5=8{/tex} points, i.e, {tex}A_1, A_2, A_3, A_4 ...A_8{/tex} on AX, such that {tex}AA_1 = A_1A_2 = A_2A_3 = A_3A_4 ... = A_7A_8{/tex}\tJoin A{tex}_8{/tex}B\tFrom A3, draw {tex}A_3P || A_8B{/tex} which intersects AB at point P [ by making an angle at A3 equal to {tex}\\angle AA_8B{/tex}\xa0\tThen, P is the point on AB which divides it in the ratio 3:5. So, {tex}AP : PB = 3:5{/tex}Justification: In {tex}\\triangle ABA_8{/tex}, we have {tex}A_3P || A_8B{/tex}\xa0{tex}\\therefore \\frac{AP}{PB}=\\frac{AA_3}{A_3A_8}{/tex} [ by basic proportionality theorem]By construction, {tex}\\frac{AA_3}{A_3A_8}=\\frac{3}{5}{/tex}\xa0Hence, {tex}\\frac{AP}{PB}=\\frac{3}{5}{/tex} | |
