Question

find the roots of the following quadratic equations by factorisation .

1) x²+4x-5=0


please help me i give you 20 thanks don't spam...​

Answer 1

Answer:

${x}^{2} + 4x - 5 = 0$

${x}^{2} + 5x - x - 5 = 0$

x(x+5)-1(x+5)

(x-1)(x+5)

hence root of quadratic equation is

(x-1)=0

×=1

or

(x+5)=0

x=-5

please mark me as brilliant
