find the value of x from the below equation : x ^ 2 − 7 x + 10 = 0
"here we need to find out a and b such that a + b = - 7 and ab = + 10 a = - 5 and b = - 2 satisfies the above condition . hence x ^ 2 − 7 x + 10 = ( x − 5 ) ( x − 2 ) x 2 − 7 x + 10 = ( x − 5 ) ( x − 2 ) x ^ 2 − 7 x + 10 = 0 ⇒ ( x − 5 ) ( x − 2 ) = 0 x 2 − 7 x + 10 = 0 ⇒ ( x − 5 ) ( x − 2 ) = 0 step 3 : equate each factor to 0 and solve the equations ( x − 5 ) ( x − 2 ) = 0 ⇒ ( x − 5 ) = 0 or ( x − 2 ) = 0 ⇒ x = 5 or 2 a"
divide(subtract(7, sqrt(subtract(power(7, 2), multiply(10, 10)))), 2)
