To solve the expression (2(3a + 4) - (a - 6) - (3 - a)^2 + 4(5 - a)), first, distribute and simplify each term. Start by expanding the brackets: (2(3a + 4) = 6a + 8), (- (a - 6) = -a + 6), and (- (3 - a)^2 = - (9 - 6a + a^2) = -9 + 6a - a^2). Combine all the terms, collecting like terms to simplify the expression to its final form.

x^(2) - 10x + 16 = 0 Factors of '16', which are, 1,2,4,8,16. Select two numbers from this list that add/subtract to '10' . They are '2' and '8'. Setting up brackets ( x 2)(x 8) Since '16' is positive(+), then both signs must be the same. Since '10x' is negative (-) , then both signs are negative. Hence (x - 2)(x - 8 ) = 0 When x - 2 = 0 x = 2 & when x - 8 = 0 x = 8 So the two answers are ,2, & ,8, .
