Setting to zero may help.

36 - X2 = 0

36 = X2

take square root each side

(+/-) 6 = X

What is Difference of two square?

The difference of two squares is quick way to factor polynomials when certain constraints are met: Namely that you have two squares (e.g. 4, 25, 36x2 , 144a6) and one is subtracting from the others (e.g. 25 - 36x2). IF these two constraints are met, then you are able to factor the polynomial by finding the square roots of the squares. sqrt(25)=5 sqrt(36x2) = 6x Therefore 25 - 36x2 = (5+6x)(5-6x) in factored form. In general, given any two squares, a2 and b2, AND they are subtracting, a2 - b2, you can factor them to be (a + b)(a - b).

Which of the following is an x-intercept of y -36x2 - 55x 14?

y = -36x2 - 55x + 14; since -36(14) = 4(-9)(7)(2) = 8(-63) and 8 + (-63) = -55, then y = (-36x2 - 63x) + (8x + 14); factor out -9x and 2 y = -9x(4x + 7) + 2(4x + 7); factor out 4x + 7 y = (4x + 7)(-9x + 2); let y = 0 0 = (4x + 7)(-9x + 2); let each factor equal to zero and solve for x 4x + 7 = 0 or -9x + 2 = 0 x = -7/4 or x = 2/9 Thus, the parabola cuts the x-axis at -7/4 and 2/9.
