5-8x2-5x2 is equal to -21.
-5x2+9x-4 -5x2+9x+-4 Factors of -20 that add to equal 9 are -5 and-4 -5x2+5x+4x+-4 -5x(1x+1) + 4x(1+-1x)
5x2=10
6x2-2x+36 = 5x2+10x 6x2-5x2-2x-10x+36 = 0 x2-12x+36 = 0 (x-6)(x-6) = 0 x = 6 or x = 6 It has two equal roots.
5x2 and 10x3
5x2 - 136 = 44 5x2 - 136 + 136 = 44 + 136 5x2 = 180 5x2/5 = 180/5 x2 = 36 √x2 = √36 x = ±6
5x2 + 32 cannot be simplified any more unless you had an equal sign and a number or x on the other side of the equal sign.
Assuming that the 2 in "5x2" is a power (5x2), then no, this is not a linear equation. It is a parabolic equation.
4x2 + 1 + x2 + 3 = 5x2 + 4
5x2(1 + x)(1 - x)
5x2 + 3x - 1 does not have rational factors.
