6x² +13x + 2
(6x + 1)(x + 2)
First look on the signs and indications interior the equation 2x^2 "-" 13x "+"15 meaning that's it extremely is an x- even though circumstances an x - even though to start. Then use 2 numbers that equivalent 15 while prolonged via one yet another. There are 2 opportunities, 15x1 or 3x5, because of the fact the 2d term is -13, and th first term is +2 is it ordinary to be certain that 15x a million is out, so now, a thank you to place them interior the excellent place. (2x-3)(x-5) utilising the foil approach, ( first, exterior, interior, final.) examine the mathematics to be certain that 2x X x = 2x^2 and that 2x X -5= -10x then -3 X x is-3x and -3 X -5 is +15 including the comparable words makes it 2x^2-13x+ 15
2 + 13x + 6x^2
= 6x^2 + 13x + 2
= 6x^2 + 12x + x + 2
= (6x^2 + 12x) + (x + 2)
= 6x(x + 2) + 1(x + 2)
= (x + 2)(6x + 1)
Factorize that by breaking middle term if you recombine that, answer should be same
6x^2+13x+2
6x^2+12x+x+2
take common x+2
6x(x+2)+1(x+2)
(X+2)(6x+1)
2+13x+6x^2
=6x^2+13x+2
=(2+x)(1+6x) or (x+2)(6x+1) answer//
