1a) Solve the each of these equations by factorising the left hand side into a product of linear factors: (i) x^2  6x  40 = 0 (ii) 3x^2 + 20x  7 = 0 (b) For each question in part (a), check your solutions by substituting them

Factor: x^3  3/4x  1/4 The answer is: (x  1)(x + 1/2)^2 How do I learn to do that? I'd like to reread an appropriate chapter from an appropriate textbook and do practice problems. It takes experience and practiced eye. Algebra

1.3x^2+17x+10 2.5y^8125 3.a^22ab15b^2 *Please help me.You have to factor by completing. Let's look at #1: 3x^2 + 17x + 10 We have 2 and 5 as factors of the last term. What combinations can we do to arrive at the middle term?

m2/m5*m+5/m2=1 If your problem is this: (m  2)/(m  5) * (m + 5)/(m  2) = 1 (m  2) cancels out in both the numerator and denominator on the lefthand side since you are multiplying. That leaves us with this: (m + 5)/(m
