" 25."36x^(2)-12ax+(a^(2)-b^(2))=0

Solve the following quations by using qardratic formula: 36x^(2)-12 ax+(a^(2)-b^(2))=0

Solve the following quations by using qardratic formula: 36x^(2)-12 ax+(a^(2)-b^(2))=0

Factorize each of the following expressions: 9x^(2)-4y^(2)36x^(2)-12x+1-25y^(2)a^(2)-1+2x-x^(2)

Factories the following : 12x^(2) + 36x^(2) y + 27y^(2) x^(2)

If a, b, c, x, y, z are real and a^(2)+b^(2) + c^(2)=25, x^(2)+y^(2)+z^(2)=36 and ax+by+cz=30 , then (a+b+c)/(x+y+z) is equal to :

If a, b, c, x, y, z are real and a^(2)+b^(2) + c^(2)=25, x^(2)+y^(2)+z^(2)=36 and ax+by+cz=30 , then (a+b+c)/(x+y+z) is equal to :
