Question

Solve: 49x2 - 140x = -100

Answer 1

the equation is the same as
49x^2 - 140x +100 = 0
represent 140 as the sum of 2 numbers whose product is equal to the product of the co-efficient of x^2 and the constant

Answer 2

i am still confused so the answer is 0

Answer 3

Okay .. consider 140x = 70x +70x
then the equation becomes
49x^2 - 70x - 70x + 100 = 0 factorize the first two and the second two terms to get the equation in the form of (x + a)(x + b)=0 then the values of X can be got
