Question

plzz help me to solve both of these questions by factorisation .
the answers are
(i) x= 9/7 , x= -3/2
(ii) x= -3 ,x= 7/2
​

Answer 1

Put the value of x in given equations

and u get the answer

LHS = RHS

for ex - 7x^2 + 1.5x - 13.5 = 0

first put the value of x = 9/7

7×(9/7)^2 + 1.5 × 9/7 - 13.5 = 0

if 0 is not come then put second x value
