2x2 + 6x - 8 = 72 ∴ 2x2 + 6x + 64 =0 ∴ x2 + 3x + 32 = 0 This can not be factored, as x is not equal to any integer. Using the quadratic equation, we find that: x = -3/2 ± √119 / 2i
2x2 = 8x x = 8x/2x x = 4 Check: 2(4)2 = 8(4) 2(16) = 32 32 = 32
2x2 - 16x32 2x2=4-16= -12x32= -384
xxxii or XXXII in Roman numerals is equivalent to 32 and 32+18 = 50 which is L as a roman numeral
the prime factorization of 32 is 2x2x2x2x2 and the factor tree is 32 8 4 2x4 2x2 2x2
There are 2 roots to the equation x2-4x-32 equals 0; factored it is (x-8)(x+4); therefore the roots are 8 & -4.
8a - 32 8(a - 4) that is it
2X2 + 3X - 4 = 0the discriminant is,b2 - 4ac32 - 4(2)(- 4)9 + 32 = 4141 > 1this means there are two real roots to this equation
For x = -4 2x2 + x = 2 (-4)2 + (-4) = 32 - 4 = 28
16x2 = 32. 4x4 = 16. 2x2= 4. The answer is 2^5.
x2+4x-32 = (x-4)(x+8) when factored
When factored: (x+4)(x-8)
