For the following exercises, enter the expressions into your graphing utility and find the zeroes to the equation (the x -intercepts) by using 2 n d CALC 2:zero. Recall finding zeroes will ask left bound (move your cursor to the left of the zero, enter), then right bound (move your cursor to the right of the zero, enter), then guess (move your cursor between the bounds near the zero, enter). Round your answers to the nearest thousandth. 48. To solve the quadratic equation 0.3 x 2 + 2 x − 4 = 2 , we can graph these two equations Y 1 = 0.3 x 2 + 2 x – 4 Y 2 = 2 and find the points of intersection. Recall 2 n d CALC 5:intersection. Do this and find the solutions to the nearest tenth.

Formula Formula A polynomial with degree 2 is called a quadratic polynomial. A quadratic equation can be simplified to the standard form: ax² + bx + c = 0 Where, a ≠ 0. A, b, c are coefficients. c is also called "constant". 'x' is the unknown quantity
