Multiply: (5t - 3)(2t - 4). Multiply: (3x - 6)(2x + 7). Multiply: (x + 1)(x^2 - x + 1) :)
excuse you. don't say anything if your not going to help.
Hey Keona, Don't get agitated. I'll show you the method that you cn use for solving such questions...
(5t-3)(2t-4) multiply term by term 5t*2t-5t*4-3*2t+3*4 10t^2-20t-6t+12 10t^2-26t+12
(x+1)(x^2-x+1) x^3-x^2+x+x^2-x+1 x^3+1
Learn it you ask too much it is just multiplying polynomials..
(5t - 3)(2t - 4). first split the terms in the first bracket as follows 5t and -3 then write the bracket with each as follows 5t(2t - 4) - 3(2t - 4) now multiply each term in the bracket by the number outside (5t*2t - 5t*4) - (3*2t - 3*4) next carry out the individual multiplications and open the brackets as follows: 10t^2 - 20t - 6t + 12 finally simplify by combining like terms 10t^2 - 26t + 12
