Question

solve the quadratic equation by factorisation method
1) x^2+7x+10​

Answer 1

Answer:

x=5, x=2

Step-by-step explanation:

Given Equation is-x^2+7x-10=0

=>-x^2+7x-10=0

=>-(x^2-7x+10)=0

=>x^2-5x-2x+10=0         (Since by splitting'-7x')

=>x(x-5)-2(x-5)=0

=>(x-5)(x-2)=0

=>x-5=0 or x-2=0

=>x=5    or    x=2

therefore,

the roots of the given quadratic equation are 5 and 2
