Решите уравнения а) 8х(1+2х)-(4х+3)(4х-3)=2х б)х-3х(1-12х)=11-(5-6х)(6х+5)

а) 8х(1+2х)-(4х+3)(4х-3)=2х 8x + 16x^2 - (16x^2-9) = 2x 8x + 16x^2 -16x^2 -2x = -9 6x=-9 x=-9/6=-3/2=-1,5 б)х-3х(1-12х)=11-(5-6х)(6х+5)    x-3x + 36x^2 = 11 -(25 - 36x^2) x - 3x + 36x^2 - 36x^2 = 11 - 25 -2x = -14 x=7

а) 8х(1+2х)-(4х+3)(4х-3)=2х. 8х+16х²-16х²+12х-12х+9=2х. 6х=-9 х=-1,5 б) х-3х(1-12х)=11-(5-6х)(6х+5) х-3х+36х²=11-30х-25+36х²+30х. -2х= -14. х=7
