Quadratics Quiz (Factoring, Sq Root, Quad Formula)

What are the factors of x²-8x-48 = 0 and what would the x-intercepts and y-intercept be?

• (x-12)(x+4) // x-intercepts (12,0) (-4, 0).... y-int (0, -48)

• (x+12)(x-4) // x-int (-12, 4) y-int (0, -48)

• (x+12)(x+4) // x-int (-12, 0) (-4, 0)... y-int (-8, -48)

• (x-12)(x-4) // x-intercepts (12, 0) (4,0)... y-int (0, 48)

What are the factors of x²+3x = 40 and how many solutions does the equation have?

• (x+10)(x-4) and 0 solutions

• (x+8)(x-5) and 2 solutions

• (x+20)(x-2) and 1 solution

• (x+1)(x-3) and 2 solutions

Factor: 0 = x² + 2x – 3 and write the x intercepts

• (x - 2)(x + 1) x = 2 x = -1

• (x + 1)(x - 3) x = 1 x = -3

• (x + 2)(x - 1) x = 2 x = -1

• (x - 1)(x + 3) x = 1 x = -3

What is the equation that matches the graph?

• -(x+3)(x-2) = y

• -x(x-4) = y Graph goes down because a=-1

• y = -(x-2)(x+4)

• y = (x-2⁾² - 4

• x(x-4) = y Graph goes up because a = 1

Use the quadratic formula to find the solutions for
y = -x² - 5x + 12

• -4.9 and -0.1
• -8.54 and 8.54
• -0.45 and 3.55
• -6.77 and 1.77
