Question

Find the roots of the following quadratic equation by factorisation method
X^2-225 =0
2x^2+6√3 x-60 = 0
64X^2+16x +1 = 0
4X^2+4bx –( a^2-b^2) = 0

Answer 1

Step-by-step explanation:

If factorisation doesn't work you can use shri dharacharya formula/ quadratic formula i.e

X = [-b ±√(b²-4ac)]/2a

hope this helps.
