Question

Find the roots of the given quadratic equation by factorisation method and also using

quadratic formula. 3square+ 5√5 + 10 = 0​

Answer 1

Step-by-step explanation:

3x²+5/√5x+10=0

3x²+3√5x+2√5x+2(√5)²=0

3x(x+√5)+2√5(x+√5)=0

(x+√5)(3x+2√5)=0

x=-√5

x=-2√5/3

Formula method:

x=-b+/-√b²-4ac/2a

b²-4ac

=(5√5)²-4(3)(10)

=125-120=5.

x=-5√5+√5/2(3)

=-4√5/6

=-2√5/3.

x=-5√5-√5/2(3)

=-6√5/6

=-√5.
