Solve by factoring and using the principle of zero products (x – 10)(x – 6) = -3?
(x – 10)(x – 6) = -3. Expand out the brackets on the left hand side to get
x² -16x + 60 = -3. Add 3 to both sides of the equation to get
x² -16x + 63 = 0. Factorise the left hand side. Are there two numbers that add to -16 and multiply to +63? Yes, there is, -7 and -9, so the equation factors to
(x – 7)(x – 9) = 0. Since two numbers can only multiply to zero if one (or both) of them is zero. But x cannot have two different values at the same time, so they can’t both be zero.
So either x – 7 = 0 (and therefore x = 7) or x – 9 = 0 (and therefore x = 9).
Your solutions are therefore 7 and 9.
solve by factoring and using the principle of zero products (x-10)(x-6)=-3?
X^2 -10x – 6x + 60 = -3
x^2 – 16x +63 = 0
What two numbers multiply to give 63? 7 and 9
(x-9)(x-7) = 0 (check that this is correct)
x = 9 or x = 7 are the 2 solutions
